Which has the greater slope B is not the answer ...

olga nikolaevna [1]

B is the answer.

The slope i got for the table is -1 because i divided -2 by 2.

The slope i got for the graph was 0 because 0/7 is 0.

-1 < 0

Graph these equations: x+2y=6, y=-1/2x+4 How many solutions does the system of equations have?

inysia [295]

Answer:

The system has no solution

Step-by-step explanation:

we have

$x+2y=6$

Isolate the variable y

$2y=-x+6$

Divide by 2 both sides

$y=-\frac{x}{2}+3$ ---> equation A

$y=-\frac{x}{2}+4$ ---> equation B

Compare the equations

Equation A and equation B have the same slope and different y-intercept

Remember that

If two lines have the same slope, then the lines are parallel

The solution of the system is the intersection point both graphs

In this problem, the lines don't intersect, therefore, the system has no solution

using a graphing tool

Anyone know how to do it

Morgarella [4.7K]

Answer:

Surface area of cube = 6x²

surface area of cube = surface area of sphere

it means that 6x²=4πr²

x²=

$\frac{4\pi {r}^{2} }{6} = \frac{4 \pi9}{6} = \frac{4\pi3}{2} = 6\pi$

$x = \sqrt{6\pi}$

$\sqrt{6\pi} = \sqrt{k\pi}$

$6\pi = \pi \: k$

$k = 6$
