Question

What are the solutions to the system?

y = x2 + 2x – 45
y = -3x + 5

help please and show all work.

Answer 1

for number one, its x=−1−√​y+46​​​,−1+√​y+46​​​
for number two, its x=-y-5/3
hope this helps.

Answer 2

y = x² + 2x – 45
y = -3x + 5

-3x + 5 = x² + 2x – 45
x² + 5x – 50 = 0
x has two values 5 and -10
x = 5 => y = -10
x = -10 => y = 35

Good luck.
