Tim had a collection of 700 movies at the beginning of the summer. after the summer, tim had traded some of his movies and now he has only 672 movies. what is the percent decrease of his movie collection?

4%

Step by Step Explanation

First you are going to divide 700 by 7 to get 100.

100 Will be the Percentage in this situation to make it easier.

You will then divide 672 by 7 as well to make it fair.

The answer to 672 divided by 7 equals 96

So now you have 96/100%

But you want how much he sold, not how much he had left.

So you want to subtract 96 from 100 to get 4.

4% is the amount that Tim sold that summer.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
