What is the solution to the system of equations? 2x – y = 7 y = 2x 3
velikii [3]

Answer:

I will assume the second equation is y=2x^3.  If it is y=2x+3 or y=2x-3, the lines will never intersect:  they have the same slope (2):

Step-by-step explanation:

2x – y = 7 can be rewritten as:  y = 2x -7.  It has a slope of 2.  The second equation, y = 2x 3, isn't clearly written.  If the 3 has a plus or minus sign, then the lines will never intersect:  they have the same slope, 2.

I'll assume the second equation is y=2x^3.

The formula for the volume sphere is V=4/3pie r^3 what is the formula solved for r?
oksian1 [2.3K]

Answer:

r = \sqrt[3]{\frac{3V}{4 \pi}}

Step-by-step explanation:

From the formula of volume of a sphere we have to isolate "r" on one side of the equation i.e. we have to make "r" the subject of the equation.

V=\frac{4}{3} \pi r^{3}\\\\ \text{Multiplying both sides by 3/4 we get}\\\\\frac{3V}{4} = \pi r^{3}\\\\ \text{Dividing both sides by } \pi \\\\ \frac{3V}{4 \pi} = r^{3}\\\\\text{Takeing cube root of both sides}\\\\\sqrt[3]{\frac{3V}{4 \pi}} = r

Therefore:

r = \sqrt[3]{\frac{3V}{4 \pi}}
