Answer: the answer should be B
Answer:
B. c <_ 250
Step-by-step explanation:
NO MORE THAN 250 = AT MOST 250 = less or greater than.
y=-2x+8
y=x-1
Solve y=-2x+8 for y
Substitute -2x+8 for y in y =x-1
y=x-1
-2x+8=x-1
Add -x to both sides
-2x+8+-x=x-1+-x
-3x+8=1
Add -8 to both sides
-3x+8+-8=1+-8
-3x=-9
Divide both sides by -3
-3x/-3=-9/-3
x=3
Substitute 3 for x in y =-2x+8
y=-2x+8
y=(-2)(3)+8
Simplify both sides of the equation
y=2
Answer : y=2 and x=3
(3,2)
I hope that's help !
This question is out of context
Answer:
Step-by-step explanation:
For question 1: x = -4, y = -4; x = -2, y = -2; x = 0, y = 0; x = 2, y = 2; x = 4 y = 4.
Basically, just put the same numbers under each of them.
For question 2: I think the graph needs to be bigger, if Im not wrong.
