Thank you for the opportunity to help you with your question! Hope your day is going well!

the absolute value signs are |  |

When you take the absolute value, you make whatever is in the absolute value sign positive.

So the absolute value of -24 is as follows

|-24|

Then |-24|=24.

Please let me know if you need any clarification. I'm always happy to answer your questions. Leave a positive review if you are happy!

Graphing the integers -18, 4, -20, -2, -6, 0 on a number line.

Then write the integers in order from least to greatest.

x=-10

you just have to substitute that x value into 44(x)

44(-10)=-440

What is substituting again?

When you have negative numbers, the lower the number, the higher the number is.

-20,-18,-6,-2,0,4

Remember, x is just a representation of a number.

We are looking at the specific case for when x=-10

Our equation is 44x..for simplicity, let's call it

f(x)=4x

Let x=-10

f(-10)=44(-10)=-440.
