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.
If you meant -3x then the answer is (2,12)
Answer:
55/100
Step-by-step explanation:
Multiply 20 by 5 to get 100 so you multiply 11 by 5 to get 55
parenthesis first -3-11.5
then subtract so your answer is -14.5
