<h3>
Answer: 74</h3>
==================================================
Work Shown:
h(x) = 7x-5
h(2) = 7(2)-5
h(2) = 14-5
h(2) = 9
f(h(2)) = f(9)
f(x) = x^2-7
f(9) = 9^2-7
f(9) = 81-7
f(9) = 74
f(h(2)) = 74
-----------
Here's a slightly alternative approach:
f(x) = x^2 - 7
f(h(x)) = ( h(x) )^2 - 7
f(h(x)) = ( 7x-5 )^2 - 7
f(h(2)) = ( 7*2-5 )^2 - 7
f(h(2)) = ( 14-5 )^2 - 7
f(h(2)) = ( 9 )^2 - 7
f(h(2)) = 81 - 7
f(h(2)) = 74

Answer:
-16
Step-by-step explanation:
The absolute value function gives the positive value of the argument, so this is ...
-4|-4| = -4·4 = -16
x-y=13
x=13+y--(1)
4x+2y=10
2x+y=5
26+2y+y=5
3y=-21
y=-7
Substituting value of y in equation (1)
x=13-7
x=6
Answer:
12 magazines
Step-by-step explanation:
cost over magazines
<u>12.00</u> = <u>36.00</u>
4 ?
12*3=36 whatever you do to the numerator you do it to the denominator
