If the sum of two numbers is 15 and their quotient is 4, what are they?

3, 12

Step-by-step explanation:

"x" is the larger number,

"y" is the smaller number.

Given

x + y = 15

x / y = 4

manipulate the equations for the problem

x / y = 4

*y        *y

x = 4y

solve the system of equations by the methord of substitution:

x + y =15

4y + y = 15

5y = 15

y = 3

Subsitute back into the equations given.

x = 4y

x = 12

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
