You can divide 20 by 10 and you should get 2, or do 20 divided by 2 and get 10.

Sam looked at two points that were graphed on a vertical number line. He saw the points −2 and 1.5. He wrote the following descr
yawa3891 [41]

Answer:

The correct statement would be: The positive number is 1/2 unit less than the opposite of the negative number.

Step-by-step explanation:

All stamemts are true except for the last one:

<em>The positive number is 1/2 unit more than the negative number.</em>

We can see in the plot that 1.5 is above zero and -2 is below zero.

So, -2<1.5

The opposite number of -2 is 2 and we can see that opposite number is 1/2 greater than 1.5. So, -2<1.5<2

Help i don’t understand this
Katena32 [7]
In order to find out what the blank of your expression is,, we must solve for y. We can start doing this by distributing -2 through the parenthesis.
y - 4 = -2x - 6
Now you need to move the constant to the right side and change its sign.
y = -2x - 6 + 4
Calculate the sum of -6 + 4.
y = -2x - 2
Since we cannot simplify this down any further,, y is going to equal -2x - 2. 
Let me know if you have any further questions.
