The equation is 12.5n where n stands for any hour that Phil is riding his bike. I'm using the nth term here though.
Answer:
-4
Step-by-step explanation:
if you graph it, we can find out two points are 0,17 and 1,13
we can find the slope from rise/run
Answer:
-3(x+1)² + 2
Step-by-step explanation:
-3(x+1)² + 2 because the +2 indicates the y value of the turning point and the turning point is a maximum meaning the coefficient must be negative leaving this answer
C = (5,4)
D = (4,2)
Dilation with factor 8 => for the same x, y increase by a factor of 8
=> C' = (5, 8*4) = (5, 32)
=> D' = (4, 8*2) = (4, 16)
slope of C'D' = [32 - 16] / [5 -4 ] =16
You can also see that the slope of CD = [4 - 2] / [5 - 4] = 2
Then, the new slope is 8 times the old slope, this is it was multiplied by the same factor, 8.
Answer: 16
