What are the options ???
Step-by-step explanation:
Hi there
9a + 3(8-2a)
9a + 24 - 6a
(9a -6a) +24
3x + 24
I hope that's help !
That's easy if there is 100 chairs there would be 10 rows with ten chairs in each row
-5 is on the left side of zero (negative) and 5 is on the right side of zero (positive). So, 5 is the answer...
I will assume that we are trying to find the slope between (-9,2) and (9, 2)
The slope's equation ⇒ 
<u>Let's set the variables</u>:
(x1, y1) --> (-9, 2)
(x2, y2) --> (9, 2)
<u>Now let's plug them in:</u>

<u>Thus the slope of the line is 0.</u>
Hope that helps!
