x=16

Step-by-step explanation:

9x+30-30=180-30 (you want to get x to be by itself)

9x/9=150/9

x=16.667

x=16

H (t) = 2t - 2 g(t) = 4t + 5 Find (h(g(t))

ASHA 777 [7]

Answer:

$h(g(t))=8t+8$

Step-by-step explanation:

We are given the two functions:

$h(t)=2t-2\text{ and } g(t)=4t+5$

And we want to find:

$h(g(t))$

So, by substitution, we acquire:

$h(g(t))=2(4t+5)-2$

Distribute:

$h(g(t))=8t+10-2$

Simplify:

$h(g(t))=8t+8$
