Hey there! :)
Answer:
y = 11.
Step-by-step explanation:
Set both of the equations equal:
5x - 9 = x² - 3x + 7
Rearrange the equation:
0 = x² - 3x - 5x + 9 + 7
Combine like terms:
0 = x² - 8x + 16
Factor:
0 = (x -4)²
Solve for x:
0 = x - 4
x = 4.
Plug this into an equation to solve for 'y':
y = 5(4) - 9
y = 20 - 9
y = 11.
The answer is D because the first number doesn’t reapeat

Answer:
Step-by-step explanation:
So in order to determine the factors of the given expression above, here is the step by step process.
Firstly, we need to know the factors of -8 that when multiplied together will result it -8. So after, I have listed it, I found out that it is -2 and +4.
So let us check. So the factors for this would be (3x-2)(x+4). When you multiply these factors, the result would be <span>3x2 + 10x - 8. Hope this answer helps.</span>
