The answer is 18.2
I got the answer by solving it
1. all functions are relations.
2.
-7 + 3(-12) ÷ (-3)
-7 - 36 ÷ -3
-7 - (-12)
-7 + 12
5
3.
f(n) = n² - n f(-4)
f(-4) = -4² - (-4)
f(-4) = 16 - (-4)
f(-4) = 16 + 4
f(-4) = 20
hope this helped, God bless!
Form an equation then solve:
8x+15=7
8x=-8
x=-1
The answer is $246.73 Just for whoever is trying to pass those Apex tests!
