Answer:
f(1) = 1
Step-by-step explanation:
To evaluate a function, you see the y value it gives when you plug in the x value.
When you plug in 1 for the x value, the y value is also 1, so f(1) = 1
x=9
y=15
Its a parallel gram, so the sides would be the same as the parallel side,
Answer: x = 30
2/12 x 5/x
(Cross Multiply)
2x = 60
x = 30
Answer: -1 because - 13 - 11 will = -1
