Which of the following (x,y) pairs is the solution for the system of equations x+2y=4 and -2x+y=7
kakasveta [241]

Answer:

(-2 ,3)

Step-by-step explanation:

Step 1: Rewrite first equation

x = 4 - 2y

-2x + y = 7

Step 2: Substitution

-2(4 - 2y) + y = 7

Step 3: Solve <em>y</em>

-8 + 4y + y = 7

-8 + 5y = 7

5y = 15

y = 3

Step 3: Plug in <em>y</em> to find <em>x</em>

x + 2(3) = 4

x + 6 = 4

x = -2

The volume of a cone with a height of 4 cm is 12π cubic cm. What is the radius of the base?
blondinia [14]

Answer:

r = 6cm

Step-by-step explanation:

Solve for r:

v =  \frac{1}{3} \pi {r}^{2}

12\pi =  \frac{1}{3} \pi {r}^{2}  \\ 12\pi =  \frac{\pi {r}^{2} }{3}  \\ 3 \times 12\pi = \pi {r}^{2}  \\ 36\pi = \pi {r}^{2}  \\  \frac{36\pi}{\pi}  =  \frac{\pi {r}^{2} }{\pi}  \\  \sqrt{ {r}^{2} }  =  \sqrt{36}  \\ r = 6
