Answer:

Those markings represent "absolute value"

It basically means to remove any negative sign in front of a number, and to think of all numbers as positive.

It means to find the absolute value of a number.

E.g. |-7| = 7
E.g. |59| = 59

The absolute value of a number refers to the distance of a number from the origin of a number line.

All negative numbers become positive!!!

Which line contains the point (0, 3)?
tankabanditka [31]
There are many lines which could harbour such a point...

One example which comes to mind is:

y=x+3

Equally, the line y=2x+3 could also be a possibility. You could find other possible lines which would harbour this point... As long as when x=0, y=3, your answer would be correct.

Which two expressions are equivalent to 8(6x + 9)
liraira [26]
<h3>Answers:   Choice A and Choice E </h3>

Explanation:

The distributive property allows us to go from the original expression to choice A. We multiply the outer term 8 by each term inside the parenthesis.

In general, the distributive property is a(b+c) = ab+ac. Example: 2(3+4) = 2(3)+2(4) = 6+8 = 14.

After simplifying the expression in choice A, it leads directly to choice E. This is because 8(6x) = 48x and 8(9) = 72.

Side note: A common mistake students do is to multiply the outer term by only one of the terms inside the parenthesis, while forgetting about the other term inside. Choice B shows this mistake. It's possible your teacher put choice B in there as a trap/trick answer.
