Answer:
In the given equations, "m" represents the slope of the line and "b" represents the y-intercept.
Part A includes four different equations, and they all have different values for "m" and "b". However, since there is no information about any changes in the equations or the values of "m" and "b", it is not clear which equation is being referred to in Part B.
Therefore, without additional context, it is impossible to determine whether "m" or "b" will change in the equation.

What is the value of x?
Enter your answer in the box.
Two intersecting lines. The angle formed at the top is labeled 3 x plus 50 degrees. The angle formed at the bottom directly opposite it is labeled 6 x minus 10 degrees.
Answers
We know that the two angles are opposite and therefore are equal, so we can set them equal to each other and solve for x:
3x + 50 = 6x - 10
Adding 10 to both sides, we get:
3x + 60 = 6x
Subtracting 3x from both sides, we get:
60 = 3x
Dividing both sides by 3, we get:
x = 20
Therefore, the value of x is 20.

100 students are interviewed to see which of biology, chemistry or physics they prefer.57 of the students are girls. 34 of the girls like biology best.27 of the boys prefer physics.20 out of the 28 who prefer chemistry are girls.What percentage of the students prefer biology?
Answers
Answer:
42%
Step-by-step explanation:
I think it's 42% because out of the 57 girls 34 prefer biology,20 prefer chemistry then it means the remaining 3 prefer physics. There's 43 boys, 8 prefer chemistry,27 prefer physics which leaves us with 8 boys who maybe prefer biology. Therefore:

For an equation of the form ax^2 + bx+ c = 0, where the graph crosses the y-axis once and does not intersect the x-axis. Describe the solution(s) of the equation.
(picture)
Answers
Answer:a
Step-by-step explanation:
The solution to the equation ax² + bx + c = 0 , has a graph that crosses the y-axis once and does not intersect the x-axis, then the equation has one real root and two complex conjugate roots that lie on either side of the axis of symmetry.
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
If the graph of the equation ax² + bx + c = 0 crosses the y-axis once, it means that the equation has one real root. This is because when x = 0, the equation becomes:
c = 0² + 0 + c = c
Therefore, the point (0, c) is on the y-axis, which means the graph crosses the y-axis once.
If the graph does not intersect the x-axis, it means that the discriminant b² - 4ac is negative. This is because the discriminant determines the nature of the roots of a quadratic equation, and when it is negative, the roots are complex (not real) and the graph does not intersect the x-axis.
So, the solution(s) of the equation ax² + bx + c = 0 are:
x = (-b ± √(b² - 4ac)) / 2a
Since the discriminant is negative, the term inside the square root is negative, and there are no real solutions for x. Instead, the solutions are complex conjugates of the form:
x = (-b ± i√(4ac - b²)) / 2a
where i is the imaginary unit. Since the real part of these solutions is -b/2a, which is the axis of symmetry of the parabola, and the parabola does not intersect the x-axis, the complex roots will be a conjugate pair that lie on either side of the axis of symmetry.
Hence , the quadratic equation is solved

D. The fee at Bank Y will be more than the fee at Bank Z only when the checking account balance is less than $500.
Answers
Answer:
A. The fee at Bank Y will be more than the fee at Bank Z only when a customer’s balance is more than $500.
The statement best supported by the information in the table is A. The fee at Bank Y will be more than the fee at Bank Z only when a customer’s balance is more than $500.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100.
Percentage is usually denoted by the symbol '%'.
Given in the table that,
Monthly fee for bank Y = 1% of checking account balance
Monthly fee for bank Z = $5
Suppose checking account balance = $500
Then,
Monthly fee for bank Y = 1% × 500 = 5
So, when the customer’s balance is $500, then fee at Bank Y is same as that of bank Z.
So, when the customer’s balance is more than $500, then fee at Bank Y is more than that of bank Z.
Hence the option is A.

what is the average between (25,28.8,39.2,51.2,64.8,80)? Please help me!
Answers
Answer:
48.17
Step-by-step explanation:
Average = sum of numbers / number of numbers
Sum of numbers = 25 + 28.8 + 39.2 + 51.2 + 64.8 + 80 = 289
Number of numbers = 6
Average = 289 / 6 = 48.17
=>average = 289/6 = 48.167

Andy and Nick went to the amusement park. They each bought a sandwich, and Nick got a small drink. Andy had a $10 gift certificate to put toward the cost, and Nick paid the rest, which came to $44.50. A ticket costs $20.00, and a sandwich costs $6.50. How much does a drink cost at the amusement park?
Answers
Answer:
$1.25
Step-by-step explanation:
To do this problem, you need to note that they bought two of almost everything. You are also working backwards at first to get how much they spent total and then taking away the expenses.
The first step is finding how much money they spent total, and you can do this by adding the gift certificate to the price:
44.5 + 10 = $55.50
Now, you see that they each bought a ticket for $20 EACH. There were two tickets (one for Andy, one for Nick). So multiply 20 by 2 and subtract that from your total cost.
$55.50 - (2 * $20) =
$55.50 - $40 =
$15.5
They bought a total of TWO sandwiches at 6.50 each. So repeat these steps, subtracting from the number above (underlined)
$15.50 - ($6.50 * 2) =
$15.50 - $13 =
$2.5
They bought two drinks that totaled to be $2.50.
To find the cost of ONE drink, divide this number by 2:
$2.50/2 =
$1.25
Answer:
A drink costs $1.5 at the amusement park
Step-by-step explanation:
44.50 + 10 = 54.5
2 people 1 ticket = $20 1 sandwich = $6.5
20 × 2 = 40
6.5 × 2 = 13
40 + 13 = 53
54.5 - 53 = 1.5

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answers
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.
