Solution
Step 1
The opposite angles of a parallelogram are equal:
Step 2

The equation is made true by the opposite angles theorem is
85 + y = 3y - 15
or
y = 50
Answer:
f(9) =21
Step-by-step explanation:
I will assume you want to find f(9) when x=9
Let x=9
f(9) = 2(9) +3
= 18+3
=21
f(9) =21

774÷9= 86 words
If n is the first of these integers, then the other three are n + 1, n + 2, and n + 3. Then
n + (n + 1) + (n + 2) + (n + 3) = 114
4n + 6 = 114
4n = 108
n = 27
So the four numbers are 27, 28, 29, and 30.
