Answer:
C (1,0)
Step-by-step explanation:
(f + g)(x) is equal to f(x) + g(x).
So (f + g)(x) = (3x + 5) + (-2x^2 - 5x + 3) = -2x^2 - 2x + 8
which is choice C.
Answer:
The answer to this question is B
Answer:
9 tickets
Step-by-step explanation:
Let x = the number of tickets
let y = the total she spends
So y = 5 + 8 + 0.75x
If the max she can spend is 20, set y = 20 and solve for x:
5 + 8 + 0.75x = 20
13 + 0.75x = 20
0.75x = 20 - 13
0.75x = 7
x = 7 ÷ 0.75 = 9.333333333
Therefore, the max number of tickets that can be bough is 9
