Since 7 is greater than 5, you input it into the last equation.
2•(7) -7
14-7
7
The answer is 7!
D. All students in each grade. It can't be A since the survey is for the students, it defeats the purpose. It can't be B and C since those are too biased. Basing the student population on one factor like gender and sports is not logical in the context of this survey.
Answer:
y is B. 82 degrees (and for extra, x is 54 degrees)
Step-by-step explanation:
The angles shown are complementary, which means they equal 180 degrees. Subtract 73 from 180 to get 107 degrees for the other angle in this set. After that subtract 25 from 107 to get y, which is 82 degrees.
(For x, just subtract 19 from 73 to get 54 degrees.)

e).
==> f(x) = x²
So,
==> f(3x) = (3x)² = 9x²
f).
==> f(x/2) = (x/2)² = x²/4
g).
==> 3f(x) = 3x²
h).
==> 2f(x-1)+5 = 2(x-1)²+5 = 2(x² + 1 - 2x ) + 5
= 5x² + 5 - 10x + 5
= 5x² - 10x + 10
