Answer:

$y = 8 \: \: \: x = - 10$

Step-by-step explanation:

$4( - 6x - 9y = - 12) \\ 3(8x + 9y = - 8) \\ \: \: \: \: \: \: \\ - 24x - 36y = - 48 \\ 24x + 27y = - 24 \\ \\ - 9y = - 72 \\ y = 8 \\ \\ \\ \\ \\ - 6x - 9y= - 12 \\ - 6x - 72 = - 12 \\ - 6x = - 12 + 72 \\ - 6x = 60 \\ x = - 10$

What is the volume of a sphere with a radius of 4

Ede4ka [16]

Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere which is shown below.

$V = \frac{4}{3}\pi r^{3}$

Here, we are given that our sphere has a radius of 4 units.

So plugging into the formula, we have $(\frac{4}{3})(\pi)(4 units)^{3}$ .

Start by simplifying the exponent.

(4 units)³ is equal to (4 units) (4 units) (4 units) or 64 units³.

So we have $(\frac{4}{3})(\pi)(64 units^3})$ .

Next, we multiply (4/3)(64) which can

be thought of as (4/3)(64/1)

So multiplying across the numerators and across the denominators,

we have $\frac{256}{3} \pi units^{3}$ .

Solve 2x+7=3, its because of my homework is a level higher than it shpuld be.

Kipish [7]

2x+7=3

move 7 to the other side

sign changes from +7 to -7

2x+7-7= 3-7

2x= 3-7

2x= -4

divide both sides by 2 to get x by itself

2x/2= -4/2

answer:

x= -2
