|DF| = |DE| + |EF| |DF| = 9x -36 |DE| = 47 |EF| = 3x+10 Substitute: 9x - 39 = 47 + 3x + 10 9x - 39 = 3x + 57 |+39 9x = 3x + 96 |-3x 6x = 96 |:6 x = 16 Put the value of x to the equation |EF| = 3x + 10 |EF| = (3)(16) + 10 = 48 + 10 = 58 Answer: |EF| = 58

12x2= $24
24+28+45= $97
So $97 is 100%
So 100%-30% =70% (30% off)
(note: 70% = 70/100 = 0.7)
97 x 0.7 = $67.90
A .E is 7 inches for the left arm
E is 8 1/2 inches for the left foot
the inputs look like the length of the arm (ie x)
the outputs are the length of the foot
<span>rate of change=<span>change in y change in x</span></span> use the data you gathered or this equation they give you = 0.860 • + 3.302
B. find the difference in y, then the difference in x, then divide (y over x) to get the slope
8-7/7 1/2-6 1/2
= 1/1
=1
C.you plug in any (x,y) point you used to find the slope
Solve for B
y = mx+b
y = 1*x + b
7.5 = 1*8 + b
b =
7.5 - 8 = -0.5
<span>y = x - 0.5</span>
Hope this helps
