Answer:
Soda costs $1.15 and taco costs $0.95.
Step-by-step explanation:
x + y = 2.1
2x + 3y = 5.15
Multiply the first equation by -2 to eliminate x
-2x - 2y = -4.2
2x + 3y = 5.15
Add
y = 0.95
Find x with the original first equation
x + y = 2.1
x + 0.95 = 2.1
x = 2.1 - 0.95
x = 1.15

Answer:
The correct answers are c. p(f(x)) = -.064x^2+64x-60
and b. 15,940.
Step-by-step explanation:
This is correct on the test
Answer:
x + y = 5
<u>3x - 4y = 8</u><u> </u><u> </u><u> </u>
3x + 3y = 15
<u>3x - 4y = 8 </u>-
7y = 7
y = 1
x + y = 5
x + 1 = 5
x = 4
x = 4
y = 1
Hope it helps!
