Answer:
23y-8
Step-by-step explanation:
First add together all of the terms that are next to a variable:
2y+10y+5y+6y=23y
Then add together all of the integers that are alone:
-9+10+(-7)+(-2)= -8
Add the two terms together and you get:
23y-8
The inverse of the funtion <span> f(x) = 4x
</span><span> f(x) = 4x
y = 4x
Swap out x with y
x = 4y
x / 4 = y
y = x / 4
Looks like none of the answer you have given are correct.

Answer:
D 36
Step-by-step explanation:
<em>Write the information algebraically</em>
c = 3a
c + a = 48
c = children, a = adults
<em>In the second sentence (in bold), we can replace c with 3a</em>
c + a = 48 → 3a + a = 48
<em>Simplify</em>
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
<em>We can then substitute or plug in a = 12 into the original equation:</em>
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
<h3>There are 36 children</h3>
