F(g(x))
sub g(x) for every x in f(x)
f(g(x))=2(g(x))-4
f(x^2)=2(x²)-4
f(g(x))=2x²-4
Answer:
Step-by-step explanation:
12. 40h + 100 = 300

answer is C
14. e + 3e = 24
4e = 24
e = 6
16. 3p + $4.29 = $8.94
3p = $4.65
p = $1.55
answer is B
17. 2x + 2x + x - 6 = 74
5x - 6 = 74
5x = 80
x = 16
2(16) = spearmint gum
answer is D
15. x + 2x + 10 = 76
3x + 10 = 76
3x = 66
x = 22 years old
2(22)= 44 years old
18. 2x + 26 = 54
2x = 28
x = 14
answer is B
