The segment addition postulate tells you that

... JK + KL = JL

a) Filling in the given information, you have

... 3n + (5n-7) = 25

... 8n = 32 . . . . . . . . . . . collect terms, add 7

... n = 4 . . . . . . . . . . . . . divide by 8

b) Now, you know that

... JK = 3n = 3·4 = 12

... KL = 5n-7 = 5·4-7 = 13

The segments are: JK = 12; KL = 13.

How can you tell when an equation in one variable has infinitely many solutions or no solution?

Masteriza [31]

Answer:

A system has infinitely many solutions when it is consistent and the number of variables is more than the number of nonzero rows in the rref of the matrix. For example if the rref is ��has solution set (4-3z, 5+2z, z) where z can be any real number.

Solve x - 3 < -1. Graph the solution.

LuckyWell [14K]

Answer: x < 2

Explanation: To solve for x in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.

Since 3 is being subtracted from x, we add 3

to both sides of the inequality to get x < 2.

Before we graph, write your answer in set notation.

We can write this as {x: x < 2}.

It's important to understand what this means.

This means that any number less than 2 is a solution to this inequality.

I have graphed the inequality for you below.

Start with an open dot on +2.

We use an open dot because +2 is not included as a solution.

Then draw an arrow going to the left.
