2x-7y=0
2x=7y
x=7/2y
Substitute that into x-6y=-5
7/2y-6y=-5
-2.5y=-5
y=2
x=7/2 x 2 = 7
x=7, y=2
Hope this helps.

Step-by-step explanation:
I would plug in N as any number just to see if they are equal. I did 5.
<u>A</u>. 28(5)-35= -105
<u>B</u>. 28(5-35)= -840
<u>C. </u>28(5-7)= -56
<u>D. </u> 7(4*5-35)= -105
<u>E. </u>7(4*5-5)= 105

Step-by-step explanation:
V=4/3pie(7)^3
Using it's concept, it is found that the average rate of change of the function over the interval is of 0.
<h3>What is the average rate of change of a function over an interval?</h3>
It is given by the change in the output divided by the change in the input.
In this problem, in the interval from x = -2 to x = 0, the input remains constant at - 1, hence:
The average rate of change of the function over the interval is of 0.
