I think the variation is x. because for have the y-intercept if yo move x
Answer: 9" by 7"
Step-by-step explanation:
let the dimensions of the rectangle be x and y
equation 1: xy=63
equation 2: 2(x+y)=32
first, rearrange the terms
(1′): y=63/x
(2′): y=16−x
(1′)-(2′): 0=63/x−16+x
multiply the equation by x
0=x2−16x+63
0=(x−9)(x−7)
so x = 7 or x = 9
from this, y = 9 when x = 7 and y = 7 when x = 9
so, the dimension of the rectangle is 9″ by 7″
Point-slope form: y-y1=m(x-x1)
y-2 = -8(x+8)
y-2 = -8x-64
y = -8x-62
Perpendicular = reciprocal
-8 becomes 1/8
Answer: y = (1/8)x - 62
The graph is raised by the value of that constant (if it is negative, it is lowered by that much)
One answer to this solution can be
3x80=240
