How to solve this. I am very confused.

To solve, we will need to plug in -5 for x in both instances.

|-5 + 2| / -5 + 2

|-3| / -3

Now, these absolute value bars may be a bit puzzling. What we have to do is take the absolute value of the number inside of the brackets. Meaning, that if the number is negative, we make it positive, and if the number is positive, then it stays positive.

3 / -3

-1

Hope this helps!! :)

Answer:

-1

Step-by-step explanation:

Plug in the value for x (-5) into the equation: \frac{|(-5)+2|}{(-5)+2}

Simplify:\frac{|-3|}{-3}

Take absaloute value to simplify further:

(All absaloute value means (which is what these bars represent: | |) is how far away a number is from zero, so the number will always be its positive counterpart if it is not already positive):

\frac{3}{-3}

Now simplify (divide 3 by -3) to get your answer:

-1

Which of the following represents a function?
Hitman42 [59]

Answer: C, a set of coords is only a function if it passes the vertical line test

Step-by-step explanation:

This is essentially the vertical line test. No two sets can have the same x value because it will fail the vertical line test. In answer a, -4 correlates to two y values. It fails the line test

B easily fails the test just by visually looking at it. It fails the line test

C has different x values so this looks promising. It passes the line test

D has the number 5 correlating with multiple y values. It fails the line test

Richard Hoskins was the leader of a 4-H club with 27 children. When he divided the club into groups of 5 to play a game, how man
kotykmax [81]

Answer:

5 groups

2 extra children

Step-by-step explanation:

The computation of a number of groups and number of extra children is shown below:

Given that

There is 27 children

And, this group would be divided into group 5

So,

As we know that 25 is easily divided by 5

So there are 5 groups

And, the extra children is

= 27 - 25

= 2 chidren

A cell phone carrier charges a fixed monthly fee plus a constant rate for each minute used. Part 1. In January, the total cost f
rjkz [21]

Answer:

The constant charge for each minute used is $50

Step-by-step explanation:

In order to solve this problem we will need to set two variables up. In this case:

F = constant Fee

R = rate per minute used

So the cost for the month of January is calculated like this:

F+300R=68

and the cost for February is calculated like this:

F+275R=66.5

So no we have a system of equations we can solve simultaneously. This can be solved by using different methods, elimination, substitution, graphically or by using matrices. I will solve this by substitution.

So let's solve the first equation for R:

R=\frac{68-F}{300}

and let's substitute this first equation into the second equation:

F+275(\frac{68-F}{300})=66.5

and now we can solve this for F:

F+11(\frac{68-F}{12})=66.5

We can multiply both sides by 12 so we get:

12F+11(68-F)=798

12F+748-11F=798

F= $50
