Answer:
y = -4/3 x=-1/3
Step-by-step explanation:
y = x2 + 2x – 3 and y = x – 1
y= (y + 1)2 + 2(y + 1) - 3 and x= y+ 1
y= 2y + 2 + 2y +2 and x= y+ 1
-3y = 4 and x= y+ 1
y = -4/3 and x = (-4/3) + 1 = -1/3
x2 is x squared or x multiplied by two
Answer:
(- 2, - 3) and (1, 0)
Step-by-step explanation:
The solution to a system of equations given graphically are at the points of intersection of the 2 graphs.
The solutions are therefore (- 2, - 3 ) and (1, 0 )
