MULTIPLE CHOICE
y=2x-2
y=x^2-x-6
A. (-1, -4) and (4,6)
B (-1, -5) and (4,2)
C (0,2) and (2,2)
D (-2,0) and (3,0)

A

Step-by-step explanation:

y=2x-2 1

y=x^2-x-6 2

2x-2 = x^2-x-6

x² -3x -4=0

x= -1 and x=4

at x=-1

to equ--1 y= -4

to equ---2 y= -4

x= 4

to equ--1 y= 6

to equ---2 y= 6

-50/3 is the final answer! : )

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make
