Answer:
The answer is D, your welcome
Answer:
No mistake
Step-by-step explanation:
2x + y = 5
x - 2y = 10
y = 5 - 2x
x - 2(5 - 2x) = 10
x - 10 + 4x = 10
5x - 10 = 10
5x = 20
x = 4
2(4) + y = 5
y = -3
She made no mistake
You can check by plugging in x = 4 and y = -3 into the original equations . They fit exactly.
2x - 11 is the answer because you don’t know what x is equal to
Answer:
- 
Step-by-step explanation:
Given
f(x) =
- 
Evaluate f(19) by substituting x = 19 into f(x)
f(19) =
- 
=
