Please help i have to finish 15 assignments today including a final exam and i dont know what im doing
Sergio039 [100]

Answer:

(-1,6) ; (-2,11)

Step-by-step explanation:

y= x^2-2x +3

y= -5x + 1

the best way to proceed is substitute the value of y shows in the second equation in the first equation (general rule: substitute the value shows in the linear equation in the quadratic equation)

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

x^2 +3x + 2 = 0

(x+2)(x+1) = 0

x = -2

x = -1

Solution 1

x = -1

y = 5 + 1 = 6

Solution 2

x = -2

y = 10 + 1 = 11

Step-by-step explanation:

Coordinates are listed as (x,y) so x = -5 and y = .5

(-5) - 4(.5) = -7

-5 - 2 = -7

-7 = -7

Marking as Brainliest is much appreciated.
