Given h(x) = -5x – 1, solve for x when h(x) = -6.
Answer:
h(x) = 1
Step-by-step explanation:
h(x) = both of these equations, but really only -6. Plug in 1 to x in the equation and it will equal -6.
Hope this helps
The value of x when h(x) is 6 can be obtained by replacing h(x) with 6 and solving for x in this case we get x is equal to - 7/5.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, h(x) = - 5x - 1.
Now, to solve for x when h(x) = 6 we'll simply replace h(x) with 6.
∴ h(x) = - 5x - 1.
6 = - 5x - 1.
5x = - 1 - 6.
5x = - 7.
x = - 7/5.

The teacher has presented the problem 5 + 7 = ? to the class. The teacher has modeled using base ten blocks to represent the problem. The teacher observes several students as they model the problem with the manipulatives. Which model correctly demonstrates the use of the base ten blocks?
The correct model demonstrating the use of base ten blocks for the problem 5 + 7 = ? will show one ten block and two unit blocks, which represents the sum, 12.
To determine which model correctly demonstrates the use of the base ten blocks for the problem 5 + 7 = ?, follow these steps:
Represent the first number, 5, with base ten blocks. Since 5 is less than 10, you will use five unit blocks (each representing one).
Represent the second number, 7, with base ten blocks. Again, since 7 is less than 10, you will use seven unit blocks.
Combine the base ten blocks representing both numbers. In this case, you will have a total of 12 unit blocks (five from the first number and seven from the second number).
Check if any groupings of 10 can be made. Since 12 is greater than 10, you can create a group of 10 unit blocks and have two unit blocks left over.
Represent the combined number using base ten blocks. In this case, you will have one ten block (representing 10) and two unit blocks (representing 2).

What is the solution to the system of equations? y = –5x + 3 y = 1 (0. 4, 1) (0. 8, 1) (1, 0. 4) (1, 0. 8).
The solution to the system of equations (0.4, 1).
Given equations according to the question,
y = -5x+3
y = 1
Now we can use y = 1 and substitute the value of y in y = -5x+3
After substituting we get, the value of y we get,
= 1 = -5x+3
Now given points according to the questions are
(0.4, 1) , (0.8, 1), (1, 0.4), (1, 0.8).
We substitute these points in the equation to see which points satisfy the equation, the point satisfying the equation is our point.
First, we will use (0.4, 1)
= 1 = -5x+3
= 1 = -5×0.4 + 3
= 1 = -2+3
= 1 = 1
Hence (0.4, 1) is our first solution of the equation.
Then we will use (0.8 ,1)
= 1 = -5x+3
= 1 = -5×0.8 + 3
= 1 = -4+3
= 1 = -1
Hence (0.8, 1) is not out the solution to the equation.
Then we will use (1,0.4)
= 1 = -5x+3
= 1 = -5×1 + 3
= 1 = -5+3
= 1 = -2
Hence (1, 0.4) is not the solution to the equation.
Then we will use (1,0.8)
= 1 = -5x+3
= 1 = -5×1 + 3
= 1 = -5+3
= 1 = -2
Hence (1, 0.8) is not the solution to the equation.

Find on equalion of the tagert line? normat line to the curve at the givio point y=x^3/2, (1,1)
The equation for the tangent line: y - 1 = (3/2)(x - 1). The equation for the normal line: y - 1 = (- 2/3)(x - 1).
To find an equation for the tangent line, normal line to the curve at the given point y = x^(3/2), (1,1), follow the given steps:
Step 1: Finding the derivative of the curve:
y = x^(3/2)dy/dx
= (3/2)x^(1/2)
Step 2: Substituting x and y values into the derivatives, for the point (1,1)
dy/dx = (3/2)(1)^(1/2)
= (3/2)
Step 3: Using the point-slope formula, write the equation for tangent line:
y - y1 = m(x - x1)
where m is the slope of the tangent line, and (x1, y1) is the point on the tangent line.
(x1, y1) = (1,1)m
= (3/2)y - 1
= (3/2)(x - 1)
Step 4: The slope of the normal line is the negative reciprocal of the slope of the tangent line.
Hence the slope of the normal line = - 2/3
Using the point-slope formula, the equation for the normal line is given by:
y - y1 = m(x - x1)y - 1 = (- 2/3)(x - 1)
The equation for the tangent line:
y - 1 = (3/2)(x - 1)
The equation for the normal line: y - 1 = (- 2/3)(x - 1).

x - y = -3
pls help
There is no point (x, y) that satisfies both given equations simultaneously.
The system of equations is given as follows:
3x - 3y = -4
x - y = -3
Let's solve the second equation for x in terms of y:
x - y = -3
x = y - 3
Substitute x = y - 3 into the first equation:
3x - 3y = -4
3(y - 3) - 3y = -4
3y - 9 - 3y = -4
-9 = 5
The last step is not true, so the system has no solution.
Therefore, there is no solution to the system of equations 3x - 3y = -4 and x - y = -3.

. True or false. Randomization distributions are centered at the value where the null is true. True False
False. Randomization distributions are centered at the value where the null is false. This distinction is important in hypothesis testing as it helps determine the statistical significance of observed differences or effects.
Randomization distributions are generated through permutation tests, which involve random shuffling of data points between groups. In hypothesis testing, the null hypothesis assumes that there is no difference between groups or no effect of a treatment. The alternative hypothesis suggests otherwise.
The randomization distribution is created by repeatedly shuffling the data and calculating a test statistic based on the null hypothesis. This distribution represents the expected outcomes if the null hypothesis is true. Therefore, the randomization distributions are centered at the value where the null is false, as they capture the potential differences or effects between groups.
In summary, randomization distributions are not centered at the value where the null is true; rather, they are centered at the value where the null is false. This distinction is important in hypothesis testing as it helps determine the statistical significance of observed differences or effects.

Answer: no solution
Step-by-step explanation:
Answer:

Step-by-step explanation:
In order for the system to have solutions, x and y must work for both equations.
The easiest way to solve this is the isolate the y variable on both equations and then solve for x:
1. x+y=5
y=5-x
2. x+y=6
y=6-x
Since the y variables for both equations should be the same, let us make a new equation:

Find F'(x): F(x) = S3x 2 -4(t+1)^1/3 dt
The derivative of F(x) is \(F'(x) = 6 - 12(3x+1)^{(1/3)\).
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
To find the derivative of the given function F(x), we will apply the fundamental theorem of calculus and differentiate the integral with respect to x.
Let's compute F'(x):
F(x) = ∫[2 to 3x] \((2 - 4(t+1)^{(1/3))} dt\)
To differentiate the integral with respect to x, we'll use the Leibniz integral rule:
F'(x) = d/dx ∫[2 to 3x] \((2 - 4(t+1)^{(1/3))} dt\)
According to the Leibniz integral rule, we have to apply the chain rule to the upper limit of the integral.
\(F'(x) = (2 - 4(3x+1)^{(1/3)}) d(3x)/dx - (2 - 4(2+1)^{(1/3)}) d(2)/dx\) [applying the chain rule to the upper limit]
\(F'(x) = (2 - 4(3x+1)^{(1/3)}) (3) - (2 - 4(2+1)^{(1/3)})\) (0) [using the power rule for differentiation]
\(F'(x) = 6 - 12(3x+1)^{(1/3)\)
Therefore, the derivative of F(x) is \(F'(x) = 6 - 12(3x+1)^{(1/3)\).

what does it mean to say that an allele is "fixed"?
Answer:
When we say that an allele is "fixed," it means that a particular allele has reached a frequency of 100% in a population.
Step-by-step explanation:
Alleles are different forms of a gene that occupy the same position on homologous chromosomes. In a population, different alleles can exist for a specific gene. However, through various evolutionary processes such as natural selection, genetic drift, or gene flow, one allele may become predominant and eventually fixate within the population.
The fixation of an allele can occur through different mechanisms. For example, if a beneficial allele provides a selective advantage to individuals carrying it, it is more likely to increase in frequency and eventually become fixed in the population. On the other hand, genetic drift, which is the random change in allele frequencies due to chance events, can also lead to the fixation of an allele, especially in small populations.
Once an allele is fixed in a population, it means that all future generations will inherit that allele, and no alternative alleles will be present at that particular gene locus.

Ben bought a box of cookies. He gave 2/5 of it to Brandon, 1/4 to Jeremy, and he kept the rest for himself. What fraction did he keep?
Answer:
7/20?
Step-by-step explanation:
Might not be correct since I just thought of the answer in a few seconds but:
you'll need to add those together, but first you need to have those two fractions with the same denominator. since one of the multiples are 20, you'd multiply 2/5 x 4 = 8/20 and 1/4 x 5 = 5/20. Add these two together and you'll get 13/20! Subtract 13/20 from 20/20 to get 7/20. So he kept 7/20 of the box of cookies.
I'm really bad at explaining too so sorry
\(\frac{2}{5}{{*4=} \atop {*4=}} \right. \frac{8}{20}\) \(\frac{1}{4}{{*5=} \atop {*5=}} \right. \frac{5}{20}\)
\(\frac{8}{20}+\frac{5}{20}=\frac{13}{20}\)
Therefore the total amount he gave away was \(\frac{13}{20}\)

The system of equations to represent the total cost, y, when x additional pieces are purchased with a basic cat tree at each store are;
y = 50x + 100 ------(eq 1)
y = 75x + 50 ------(eq 2)
How to Solve Simultaneous Equations?A) Let the total cost of the cat tree be y
Let each additional piece added be x.
Since basic tree is $100 and each additional platform costs $50, then we can say that;
y = 50x + 100 ------(eq 1)
Now, their basic cat tree starts at $50 and each additional piece costs $75. Thus;
y = 75x + 50 ------(eq 2)
B) Subtract eq 1 from eq 2 to gte;
25x - 50 = 0
25x = 50
x = 50/25
x = 2
y = 75(2) - 50

Carlisle Transport had $4,520 cash at the beginning of the period. During the period, the firm collected $1,654 in receivables, paid $1,961 to supplier, had credit sales of $6,916, and incurred cash expenses of $500. What was the cash balance at the end of the period?
To calculate the cash balance at the end of the period, we need to consider the cash inflows and outflows.
Starting cash balance: $4,520
Cash inflows: $1,654 (receivables collected)
Cash outflows: $1,961 (payments to suppliers) + $500 (cash expenses)
Total cash inflows: $1,654
Total cash outflows: $1,961 + $500 = $2,461
To calculate the cash balance at the end of the period, we subtract the total cash outflows from the starting cash balance and add the total cash inflows:
Cash balance at the end of the period = Starting cash balance + Total cash inflows - Total cash outflows
Cash balance at the end of the period = $4,520 + $1,654 - $2,461
Cash balance at the end of the period = $4,520 - $807
Cash balance at the end of the period = $3,713
Therefore, the cash balance at the end of the period is $3,713.
