We need to make a system of equations. A=Adults and C=Children.
A+C=350; this means how many people are there.
3A+2C=900; this deals with money.
We need to eliminate a variable, let's eliminate C by multiplying the first equation by -2.
-2a-2C=-700
3A+2C=900
A=200
This means there was 200 adults, which means there had to be 150 children.
Answer:
(-∞ , -6] ∪ [6 , +∞)
Step-by-step explanation:
<u>Let D be the domain of f </u>.
D = {x ∈ IR ; where x² - 36 ≥ 0}
x² - 36 ≥ 0
⇔ x² ≥ 36
⇔ x² ≥ 6²
⇔ √(x²) ≥ √(6²)
⇔ |x| ≥ 6
⇔ x ∈ (-∞ , -6] ∪ [6 , +∞)
