At a zoo, youth tickets cost $5 and adult tickets cost $9. a group that purchased x youth tickets and y adult tickets spent $90 on tickets. what is the domain of the relationship? a. x ≤ 5 b. 0 ≤ x ≤ 5 c. 0 ≤ x ≤ 18 d. x ≤ 18

Step-by-step explanation:

Let x represent the number of youth tickets purchased at the zoo.

Let y represent the number of adult tickets purchased at the zoo.

At the zoo, youth tickets cost $5 and adult tickets cost $9. A group spent a total of $90 on tickets. This means that

5x + 9y = 90

The domain of the relationship is the possible set of values of x and y that satisfies the equation. The domain of this relationship is

0 ≤ x ≤ 18

At x = 0, it means only adult tickets were purchased.

At x = 18, it means only youth tickets were purchased.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
