Question

solve the system: y=-x^2+5x+1 and y=2x+3. please tell me how you got your answer

Answer 1

you can turn it into a composite function and solve

Answer 2

nah ill use the quadratic formula

Answer 3

that actually will not solve it for you

Answer 4

do this instead 2x +3 = x^2 +5x+1

Answer 5

know what i mean?

Answer 6

Use the quadratic form to get your two x's

Answer 7

y = -X^2 + 5X +1
y = 2X + 3

2X + 3 = -X^2 + 5X + 1

X^2 - 3 X + 2 = 0
( X- 1 ) ( X - 2 ) = 0

Answer X= 1 Y= 5 , or X= 2 Y= 7

Answer 8

ah forgot about the negative in front of x^2
