You can graph multiple equations in one plot by merely superimposing them. You plot the x values against the corresponding y values. Usually, you are given an equation in this form y=f(x), where f(x) is a polynomial containing a variable of x. You assign arbitrary values of x, to get the y values and plot them together as one data point.

The point at which the graphs intersect each other is the solution of the problem.

Gary had a 40% discount for new tires. The sale price of a tire was $96.25. What was the original price of the tire? Round to th
EastWind [94]

If the price after the discount is subtracted is $96.25 then this is what you do

u times 0.40 x 96.25 which is 38.5 so since you are wanting to know what the price was before the discount you would add 38.5 to 96.25 and when you do that your answer is 134.75

but if you are just trying to get the discount from 96.25 you subtract 38.5 from 96.25

On the 7th, Andi had $48 in her account. We want to find when she had $92 less than what she had on the 7th.

First, let's find out how much $92 less is:

48 - 92 = -44

We are looking for when Andi had $-44 in her account. Looking at the number line, the day Andi had $-44 in her account was on the 14th.

The correct answer is C. The 14th.

Hope this helps!! :)
