Answer:
No solution
Step-by-step explanation:
- 4x - 4y = 1
- 4x - 4(x + 2) = 1
- 4x - 4x - 8 = 1
- - 8 = 1
Our end result is -8 = 1. This is not true, so this system of equations have no solution.
-4 and -9 is the correct answer
The vertex of f(x)=-x2+4x-8 is (2, -4)
Answer:
x=10,−10
Step-by-step explanation:
one of those two
1 cm = 20 km
so 3.5 cm would equal : 3.5 * 20 = 70 km <==
