Answer:
The answer is that x = 0 and y = -6. While this is not any of your options, the work below proves that it is correct.
In order to find these values, we can use elimination. To do so, we multiply the first equation by 5 and then add the equations together.
125x - 5y = 30
-2x + 5y = -30
------------------
123x = 0
x = 0
Now that we have this value, we can plug the value into one of the originals and find y.
25x - y = 6
25(0) - y = 6
-y = 6
y = -6
Answer:
F(0) = 2
F(-1) = 7
F(2) = 4
Explanation:
Notice where the x's are in the function F(x)
For F(0) you sub in 0 wherever there is an x, ie:
F(0) = 2(0)2−3(0)+2 = 2
The same is applied for F(-1) and F(2)

Answer:
I am not sure if I'm correct, but I got 16
Step-by-step explanation:
lets look at the formula for cylinder volume:
V=π*r^(2)*h
now, lets plug in 64
64=π*r^(2)*h
h=64/(π*r^(2))
Volume of glass cylinder is
V=((0.5r)^2)*(64/(π*r^(2)))*π
V=0.25π*r^(2)*(64/(π*r^(2)))
V=16π*r^(2)/(π*r^(2)
V=16
