Y is the answer for four right angles
Answer:
2.5mph (miles per hour)
Step-by-step explanation:
Simple, 12.5/5 = 2.5 mph (miles per hour)
Step-by-step explanation:
Given
f(x) = 8x - 9
Then
For a.
f(3y - 1 ) = 8(3y - 1 ) - 9
= 24y - 8 - 9
= 24y - 17
Now for b.
f(x) = - 23
or, 8x - 9 = - 23
8x = - 23 + 9
8x = - 14
x = - 14 / 8
x = - 7 / 4
