Answer:
The solution would be (10, -3)
Step-by-step explanation:
In order to solve using elimination, multiply the top equation by -3 and then add the equations together.
-9x - 12y = -54
9x - 5y = 3
---------------
17y = -51
y = -3
Now that we have a value for y, we can put it into either equation and solve for x.
3x + 4y = 18
3x + 4(-3) = 18
3x - 12 = 18
3x = 30
x = 10
Answer:
-26 × -1 = 26
This is your answer , pls mark me the brainliest!!
Answer:
f(g(x)) = 8x² + 18x - 8
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(- 2x - 1)
= 2(- 2x - 1)² - 5(- 2x - 1) - 15
= 2(4x² + 4x + 1) + 10x + 5 - 15
= 8x² + 8x + 2 + 10x - 10
= 8x² + 18x - 8
