Answer:

y=-x/3+2

Step-by-step explanation:

If you graph out 3x-y-7=0, you will get a line that goes through the points (0, -7), and about (2.3, 0). If you graph out y=x/3+2, you have to make sure that this line forms a 90 degree angle on the previous line, thus making this line perpendicular to the previous line.

Write two expressions that could be used to find 105% of x. ANSWER TODAY!! :) thanks
Margaret [11]

First way: x * 1.05

This computes directly what 105% of x will be.


Second way: x + (x * 0.05)

This takes x (which is 100%) and adds 5% of x to it.
