Jackson sells 15 apples (x) and 20 oranges (y) and made $76. Write and equation that represents this scenario.

15x + 20y = 76

Step-by-step explanation:

We simply substitute the numbers and multiply them by our x and y to come up with this equation.

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

pi x^2

step-by-step explanation:

pi times x squared
