The equation that models the relationship between the amount of money Sarah has left is 55- 0.65x= y
Answer:
A) -4x + 9y = 9
B) x -3y = -6
We multiply B) by 3
B) 3x -9y = -18 Then add it to A)
A) -4x + 9y = 9
-x = -9
x = 9
9 -3y = -6
3y = 15
y = 5
Step-by-step explanation:
Ok you just replace the x for a 2.
2(2)^4 - 8(2)^2 + 5(2) - 7
2(16) - 8(4) + 5(2) - 7
32 - 32 + 10 - 7
10 - 7

It's A. f(2) = 3.
