F(x)= 1/8x+3
g(x)=12-5x
write f(g(x)) as an expression in terms of x

Normally if you want to get the f(3) you would replace every x value by in. For this question you have to change each x value to the g(x) value. g(x) = 12-5x, which means you can replace the g(x) by 12-5x in the f(g(x)).

f(g(x)) = f(12-5x)

f(12-5x) = 1/8(12-5x)+3

f(12-5x) = 1.5 - 0.628x + 3

f(12-5x) = 0.628x + 3.5

f(g(x)) = 0.628x + 3.5

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
