Answer:
neither a or b
Step-by-step explanation:
a function has to have each X have a Y
a domain is paired with exactly one range value.
it has to pass the vertical line test
independent variable is X
dependant variable is Y
student name = x
colors/teachers is Y
so since there is the chance the students can have the same teacher and/or favorite color. then it is not a function
The value of y so that the line passing through (-1, 9) and (2, y) has a slope of -2 is 3.
<h3>What is the slope of a line?</h3>
The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on a straight line, the slope can be determined using a variety of approaches.
, where
and
are two points on the line.
Two points (-1, 9) and (2, y) are given, and a slope of -2.
Put the points in the slope formula to get the value of y.
![m=\frac{y_2-y_1}{x_2-x_1}\\-2=\frac{y-9}{2-(-1)}\\-2=\frac{y-9}{3}\\-6=y-9\\y=3](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C-2%3D%5Cfrac%7By-9%7D%7B2-%28-1%29%7D%5C%5C-2%3D%5Cfrac%7By-9%7D%7B3%7D%5C%5C-6%3Dy-9%5C%5Cy%3D3)
So, the value of y is obtained as 3.

Answer:
96 pages.
Step-by-step explanation:
We know that Charlie read the same amount of pages each day, if we call <u>N </u>the number of pages read each day, his first number on the list was N, the second number was N + N = 2N, the third number was N + N + N = 3N....
His mom sums up these numbers and gets 432. Therefore we have that:
N + 2N + 3N + 4N + 5N + 6N + 7N + 8N = 432
36N = 432
N = 12.
Now we know that Charlie read 12 pages per day. With this information we can conclude that by the end of the 8th day he read:
12 pages x 8 = 96 pages.
