Answer:
D
Step-by-step explanation:
The equations are
● 4x + 2y = 10 (1)
● 4x - 2y = -10 (2)
● 4x + 2y = 10
Add - 4x to both sides
● 4x + 2y -4x = 10 -4x
● 2y = 10 -4x
Divide both sides by 2
● 2y/2 = (10 - 4x)/2
● y = 5 - 2x
● y = -2x + 5 (1)
● 4x - 2y = -10
Add -4x to both sides
● 4x -2y -4x = -10 - 4x
● -2y = -10 - 4x
Divide both sides by -2
● -2y/-2 = (-10 -4x)/-2
● y = 10 + 2x
● y = 2x + 5 (2)
So the equation are
● y = 2x + 5
● y = -2x + 5

So the answer is d
Answer: 4 4/9 yards
Step-by-step explanation:
Since we are given the information that forty yards of fabric are used to make 9 school banners.
The number of yards of fabric that each banner use will be the total yards of fabric which is 40 yards divided by 9. This will be:
= 40/9
= 4 4/9 yards
Each banner will use 4 4/9 yards
Length and width. Planes are two dimensional.
