Since there are 12 inches in a foot, it would be 3/12, or 1/4.
This is asking you to rewrite the equation so that Y is alone on one side.
First, move the 4x to the other side:
4x - 5y - 4x = 9 - 4x -->
-5y = 9 - 4x
Divide both sides by -5 to get the Y alone:
-5y/-5 = (9-4x)/(-5) -->
y = (9-4x)/(-5)
You could stop there, but some people like to make the right side look a little simpler. dividing by a negative number looks a little messy, so we rewrite the equation in a few steps. All the below are all the same thing, just written in a different way.
y = -(9-4x) / 5 -->
y = (-9+4x) / 5 -->
y = (4x - 9) / 5
If change from 313 to 533
a) median: It increased by 15
b) mean: It increased by 22
They have no solutions because they have the same slope with different y variables this limits them so they won’t cross but the lines will be parallel to one another.
2y-x=6
Add x to each side
2y=x+6
Divide each side by 2
y=1/2x+3
Your two equations are
y=1/2x+1 And y=1/2x+3
