For this equation, substitute y for 1/2x-5, since y=1/2x-5.
4x+2(1/2x-5)= 0
4x+x-10=0
Combine like terms.
5x-10= 0
Add 10 to both sides.
5x=10
Divide by 5.
x=2
Now, plug in x for y.
y=1/2(2)-5
y= 1-5
y=-4
(2,-4) <=== solution
We can check this by plugging it in.
4x+2y= 0
4(2)+2(-4)=0
8+2(-4)=0
8-8=0
0=0
This works.
I hope this helps!

The answer is D.
Drops = 27
First, we need to find the volume of the given tank using the following equation
Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation
Answer:
<em>D</em>
Step-by-step explanation:
- <em>3/8 = 0.375 so that is not the answer we would eliminate that answer</em>
- <em>11/25 = 0.44 so we would eliminate that answer too</em>
- <em>C and D are left</em>
- <em>2/5 = 0.4 which we would eliminate</em>
- <em>so that means D would be our answer because 5/7 = 0.714285714</em>
- <em>which is a repeated decimal </em>
<em></em>
