Answer:
plain = $10.50
pepperoni = $12.50
Step-by-step explanation:
x = pepperoni
y = plain
3x + 2y = 58.5
2x + 4y = 67
using substitution method, I multiplied the first system by -2 to get:
-6x - 4y = -117
+ 2x + 4y = 67
-4x = -50
x = $12.50
2(12.5) + 4y = 67
25 + 4y = 67
4y = 42
y = $10.50
Answer:
r(s(-2)) = -2
Step-by-step explanation:
We are given these following functions:
Find the value of r(s (-2)).
First we find the composition of r and s functions. It is:
At x = -2
r(s(-2)) = -2
