Brainliest

y=-3x+12

Step-by-step explanation:

3x+y=12

-3x    -3x

y=-3x+12

your is awnswr is y=9. to the equation

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
