Answer:
y=1/2x+4
Step-by-step explanation:
to find the slope you need to know the change in y over the change in x
(0,4) and (8,8)
8-4/8-0
slope is 1/2
Answer:
-100
Step-by-step explanation:
D. 48
First is 2.05 times 20, which is 41. And then you add the 7 for tip, which is 48.
Answer:
39.5
Step-by-step explanation:
1.10 * 35.5 = 39.5
Solve the equation by replacing x with -7 and then -1.
Then subtract the two to find the difference and divide that by the difference between -7 and -1.
f(-7) = -7^2 + 2(-7) -8 = 49 -14 -8 = 27
f(-1) = -1^2 + 2(-1) -8 = 1 -2 - 8 = -9
Difference between 27 and -9 = -36
Difference between -1 and -7 = -6
Rate of change = -36 /-6 = 6
