Solve the system of equations:
y= 2x+1
y = x2 + 2x-8

x = ±3

Step-by-step explanation:

Put both equations equal to each other.

2x + 1 = x^2 - 8

Cancel 2x on both sides.

1 = x^2 - 8

Add 8 to both sides.

1 + 8 = x^2

Simplify 1 + 8 to 9.

9 = x^2

Take the square root of both sides.

±√9 = x

±3=x

Simplify.

x = ±3

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

i’m kinda new to precal but your answer should be 21. hope i got it right.
