write the inequality shown -4x+y=-3
The inequality corresponding to the equation -4x + y = -3 is either y > 4x - 3 or y < 4x - 3, depending on the relationship between 4x - 3 and 0.
To write the inequality represented by the equation -4x + y = -3, we first need to manipulate the equation to express y in terms of x.
Starting with -4x + y = -3, we isolate y by adding 4x to both sides:
y = 4x - 3
Now we have y expressed in terms of x. To form the inequality, we consider the relationship between x and y. The inequality depends on whether the expression 4x - 3 is greater than or less than 0.
If 4x - 3 is greater than 0, then y is greater than 0, and we can write the inequality as:
y > 4x - 3
If 4x - 3 is less than 0, then y is less than 0, and we can write the inequality as:
y < 4x - 3
The inequality represents a region in the coordinate plane where the y-values are either greater than or less than the expression 4x - 3, depending on the direction of the inequality sign.
For example, if we choose a point (x, y) in the region above the line y = 4x - 3, where y is greater than 4x - 3, the inequality y > 4x - 3 will hold true. On the other hand, if we choose a point below the line, where y is less than 4x - 3, the inequality y < 4x - 3 will be satisfied.

Your plan was to be on the road by 9 A.M. but you did not leave the garage until 10 A.M. You then drove with the cruise control set at 50 mph until stopping at noon. What was your average speed over the time interval from 9 A.M. to noon
Answer:
The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
Step-by-step explanation:
The average speed is given by the following equation:
\(v = \frac{d}{t}\)
From 10A.M. to noon.
You traveled at 50mph during 2 hours. So how long you traveled?
\(50 = \frac{d}{2}\)
\(d = 50*2\)
\(d = 100\)
You traveled 100 miles.
What was your average speed over the time interval from 9 A.M. to noon
From 9 A.M. to 10 A.M, you did not travel.
From 10 P.M. to noon, 100 miles.
So 100 miles during 3 hours.
\(v = \frac{d}{t} = \frac{100}{3} = 33.33\)
The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.

O The system has no solution.
O The system has a unique solution:

O The system has infinitely many solutions.
They must satisfy the following equation:
y=0
The system A has no solution.
The system B has the solution y=( 3-x )/3
What is the solution to an equation?
In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.
System A:
x+3y=9..........(1)
-x-3y=9 ..........(2)
(1) => x=9-3y........(3)
Substitute (3) into (2)
(2) = > - ( 9-3y ) - 3y = 9
-9 + 3y - 3y = 9
-9 =9
This is false.
So, the system has no solution.
System B:
-x-3y=-3..........(1)
x+3y=3..........(2)
(2) => x=3-3y........(3)
Substitute (3) into (1)
-(3-3y)-3y=-3
-3+3y-3y= -3
-3=-3
This is true,
So, the solution is:
x=3-3y
=> 3y= 3-x
=> y=( 3-x )/3

Ms. Clint is comparing the sales of sweaters and gloves at her store for the past ten winter weeks.
Answer:
B. A linear function with a positive slope.
Step-by-step explanation:
A correlation can be defined as a numerical measure of the relationship existing between two variables (x and y).
In Mathematics and Statistics, a group of data can either be negatively correlated, positively correlated or not correlated at all.
1. For a negative correlation: a set of values in a data increases, when the other set begins to decrease. Here, the correlation coefficient is less than zero (0).
2. For a positive correlation: a set of values in a data increases, when the other set also increases. Here, the correlation coefficient is greater than zero (0).
3. For no or zero correlation: a set of values in a data has no effect on the other set. Here, the correlation coefficient is equal to zero (0).
A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and it has a positive slope which is always constant.
From the graph, we can deduce that the scatter points lie close to a straight line with a slope that is positive.
Hence, the type of function which best models the relationship between the sales of sweaters and gloves is a linear function.
Mathematically, slope is given by the formula;
\( Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} \)
\( Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} \)

If the number of different activities is represented by four consecutive odd integers what is the algebraic expression that represents the total number of activities they had to choose from in one day
The four consecutive odd integers are: 51 , 53 , 55 and 57.
An algebraic expression (or) a variable expression is a combination of terms by the operations such as,
addition, subtraction, multiplication, division, etc.
For example, let us have a look at the expression 5x + 7. Thus, we can say that 5x + 7 is an example of an algebraic expression.
Types of algebraic expressions may further be distinguished in the following five categories. monomial, polynomial, binomial, .trinomial. multinomial.
the expression: 3/4x + y/2 (4x + 7) By using the distributive property, the given expression can be written as,
3/4x + y/2 (4x) + y/2 (7).
Simplifying an expression is just another way to say solving a math problem. When you simplify an expression, you're basically trying to write it in the simplest way possible. At the end, there shouldn't be any more adding, subtracting, multiplying, or dividing left to do. For example, take this expression: 4 + 6 + 5.The sum of 4 consecutive odd integers is 336, how do you find the largest integer? because odd consecutive integers differ from each other by 4. Value of x can be determined by adding up assumed terms and equating it with 336.

the y intersect is going to be 4
the slope is a positive 1 , going up to the right, through the positive quadrant, line is facing to the right
y = -x+6
the y intersect is going to be -6
the slope is going to be a -1 , following up the opposite way the line is going to face the left

Step-by-step explanation:
\(\overline{X} \cdot\overline{Z} +\overline{X} \cdot Y + \overline{X} \cdot Z +XY\)
\(=\overline{X} (\overline{Z}+Y+Z) +XY\)
Recall that
\(\overline{Z} + Z = 1\)
and the identity \(\boxed{A \cdot 1 = A}\), therefore
\(\overline{X} (\overline{Z}+Y+Z) = \overline{X}\) because \(\overline{Z}+Y+Z\) will always be \(1\).
Thus,
\(\overline{X} \cdot\overline{Z} +\overline{X} \cdot Y + \overline{X} \cdot Z +XY\)
\(=\overline{X} (\overline{Z}+Y+Z) +XY\)
\(= \overline{X} + XY\)
Now considering the Absorption Law,
\(( \overline{A} \cdot \overline{B}) + B = (\overline{A}+ B) \cdot (\overline{B} +B)\)
Once \(\overline{B}+B=1\), therefore
\(\overline{A} +B\)
we know
\(= \overline{X} + XY = \boxed{\overline{X} +Y}\)
Which are the roots of the quadratic function f(b) = 62 – 75? Select two options.
b=573
Ob= -573
b=35
b= -35
Ob= 253
Answer:
\(b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}\)
Step-by-step explanation:
Given
\(f(b) = b^2 - 75\)
Required
Determine the roots
To get the root of the function, then f(b) must be 0;
i.e. f(b) = 0
So, the expression becomes
\(0 = b^2 - 75\)
Add 75 to both sides
\(75 + 0 = b^2 - 75 + 75\)
\(75 = b^2\)
Take square roots of both sides
\(\sqrt{75} = \sqrt{b^2}\)
\(\sqrt{75} = b\)
Reorder
\(b = \sqrt{75}\)
Expand 75 as a product of 25 and 3
\(b = \sqrt{25*3}\)
Split the expression
\(b = \sqrt{25} *\sqrt{3}\)
\(b = \±5 *\sqrt{3}\)
\(b = \±5 \sqrt{3}\)
\(b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}\)
The options are not clear enough; however the roots of the equation are \(b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}\)
