Steps
8x−7y=−5
Add 7y to both sides
8x−7y+7y=−5+7y
Simplify
8x=−5+7y
Divide both sides by 8
8x
8 =−

y = 20x + 500
Reorder the terms:
y = 500 + 20x
Solving
y = 500 + 20x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 500 + 20x</span>
Answer:
157.5
Step-by-step explanation:
Try like this:
45 times 3.5
If the long side on both is 9ft and 3ft then 3•3 is 9 so for the short side you do the same. If the short side is 1ft and the other is "j" then it's 1•3 is 3.
1•3=3
Sorry if it's confusing the way I explained it.
Answer:
Step-by-step explanation:
There are two. This can be factored which will find both of them.
y = (x - 3)(x - 1)
x - 3 = 0
x - 3 + 3 = 3
x - 1 = 0
x - 1 + 1 = 1
x = 1
The zeros are (3,0) and (1,0)
