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:
16
Step-by-step explanation:
Evaluate the function. f(x) = 4x2 + 4x - 4 Find f(3)
f(3) = 4 x 2 + 4(3) - 4
After this step conduct PEMDAS
f(3) = 4 x 2 + 12 - 4
f(3) = 8 + 12 - 4
f(3) = 20 - 4
f(3) = 16
