Composing functions means that the input of the outer functions is the output of the inner function.
In fact, you can rewrite the circle notation as
So, we can substitute g(x) with its expression:
And since f(x)=x+5, we simply have to add 5 to its input:
Similarly, we have, substituting f with its expression,
And since g(x)=4x+2, we have to multiply the input by 4 and add 2:
Answer:
x = 4, TU = 22
Step-by-step explanation:
Given that TS bisects TU at Q , then
TQ = QU , substitute values
5x - 9 = 15 - x ( add x to both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
Thus
TU = 5x - 9 + 15 - x = 4x + 6 = 4(4) + 6 = 16 + 6 = 22

Answer:
3x36
Step-by-step explanation:
Because he is getting 36 3 times so 3x36

None of those choices is correct, because a bare naked fraction without units is not a satisfactory answer. Keeping the units makes this question easy to answer, and the answer needs units.
The question is asking for a unit rate. That always means DIVIDE.
(18 pizzas) / (12 families)
= ( 18/12 ) (pizza/family) = 1.5 pizza/family .
