Given:
The functions are:
To find:
The function 
.
Solution:
We have,
We know that,
On substituting the values of given functions, we get
Therefore, the required function is .
If the temperature changed from 17 degree F to -7 , the change was
17+7=24 degrees F
the average change was 24/12=2 , 2 degrees per hour

Answer:
the answers are:x1=-4 and x2=5
Answer:
b
Step-by-step explanation:
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
