23 is the middle number from 12 to 34.
Answer:
Yes the graphs of the lines are in pair parallel.
Step-by-step explanation:
They are in pair parallel because they do not touch each other. To find the slope of the line that is parallel to 5x+2y=6...
The first thing to do is subtract 5x since its a positive so it would look like this:
5x+2y=6
<u> -5x =-5x</u>
Next you would divide by 2 on each side so the y can be isolated:
5x+2y=6
<u>-5x =-5x</u>
<u>2y</u> = <u>-5x + 6</u>
2 2
Lastly the 2 divided by 2 gets crossed out because they cancel each other out and divide -5x by 2 and 6 by 2 then you would be stuck with this:
y= -2.5x+3
So your parallel slope would be -2.5x.
Answer:
Incorrect/No
Step-by-step explanation:
7x2=14
-7x2=-14
<u>Follow the below guidelines:</u>
- A positive number times a positive number is a positive number
- A negative number times a positive number is a negative number
- A positive number times a negative number is a negative number
- A negative number times a negative number is a positive number
Looking at the last one, we see that -2x-7=14, a positive number

You can just do the inverse operation. 39 divied by 10 = 3.9
so 3.9 *10 =39

Answer:
108 pi inches cubed
Step-by-step explanation:
The volume of a cylinder is base area times volume. Since we have our base area of 12 pi, and our height of 9, we have the are as 12* 9 = 108 pi inches cubed. Thus, the answer is D.
