Answer:

x + x + x

Step-by-step explanation:

We have 3y and are asked to express it equivalently with the answers provided.

I will go over the flaws of each answer and single it down to the correct one.

x * x * x would equal x^3, since this is being multiplied.

x^3 is equal to x * x * x, therefore it is not correct.

x + 3 is not correct because you cannot add numbers or variables that are not like terms, so it would not equal to 3y.

x + x + x would equal to 3y because they are all like terms and do not form exponents.

What is the range of the function f(x) = –2|x + 1|

Oduvanchick [21]

Answer:

$f\left(x\right)\le \:0$

Step-by-step explanation:

$\mathrm{The\:range\:of\:an\:absolute\:function\:of\:the\:form}\:-c|ax+b|+k\:\mathrm{is}\:\:f\left(x\right)\le \:k$

$f(x) = -2|x + 1|+0$

$k=0$

$f\left(x\right)\le \:0$

The cost of attending an amusement park is $10 for children and $20 for adults. On a particular day, the attendance at the amuse

Lapatulllka [165]

Using a system of equations, it is found that 10,000 children attended the park that day.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Variable c: Number of children in the park.

Variable a: Number of adults in the park.

The attendance at the amusement park is 30,000 attendees, hence:

c + a = 30,000, which is the first equation in matrix form.

Then:

a = 30,000 - c

The cost of attending an amusement park is $10 for children and $20 for adults. The total money earned by the park is $500,000, hence:

10c + 20a = 500,000, which is the second equation in matrix form.

Since a = 30,000 - c, we replace:

10c + 20a = 500,000

10c + 20(30000 - c) = 500,000

10c = 100,000

c = 10,000.

|5x|+5=45<br><br> can you explain this absloute value equation <br> i have a midterm

Ymorist [56]

So first, you get the absolute value to one side:
$|5x|+5=45\\
|5x|=40$

Next, set up two equations; One where the value inside the absolute value lines is positive, and another where it is negative, and solve both for the variable:
$|5x|=40\\5x=40\\x=\frac{40}{5}=8\\\\-5x=40\\x=\frac{40}{-5}=-8$

Your answers are 8 and -8, or +-8.

Which fraction is closer to 1 than 0

Mrrafil [7]

For some reason, you're not letting us see the choices,
so I can only give you a most general answer:

-- Any positive fraction greater than 1/2 is closer to 1 than it is to 0 .

-- No negative fraction is.
