Answer:
D
Step-by-step explanation:
a is false since x could be 0.
b is easy to check, just plug numbers in, and we can see that it's false(you would get 0+0=1 and -0-0=-1 once plugged in)
c is also easy to check, just plot the line or simplify the first equation. since (2x+2y)/2=4/2 is also x+y=2, the second equation is also x+y=2, so it must have infinitely many solutions.
d must be true due to process of elimination but let's check to make sure.
7y=14x, divide both sides by 7 to get y=2x and since they're the same equation it must mean that they have infinitly many solutions and we can see that it is correct

Is NOT RIGHT
Step-by-step explanation:
I don’t know
To solve for r, you just need to isolate r. To do that, divide by h and π on both sides:
![\frac{V}{h \pi }=r^2](https://tex.z-dn.net/?f=%20%5Cfrac%7BV%7D%7Bh%20%5Cpi%20%7D%3Dr%5E2%20)
Then, square root both sides to get rid of the 'squared':
![r = \sqrt{ \frac{V}{h \pi } }](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%7B%20%5Cfrac%7BV%7D%7Bh%20%5Cpi%20%7D%20%7D%20)
Or, if you wanted the answer in terms of π, then just don't divide by it, just divide by h and then square root it.
