Answer:
Step-by-step explanation:
Y = -x -1..........(1)
y = -2x + 7....(2)
Equating the two equations
-x -1 = -2x + 7
-x + 2x = 7+1
x = 8
Putting x in (1)
y = -8 - 1
y = -9
4z^3 + 5z^2 + z

If it was 25% off, then she paid 75% for it
75% of the original price is 170
0.75x = 170
x = 170 / 0.75
x = 226.67 <== original price
The answer is A. one solution
