Solve the following systems of linear equations using the substitution Method y = -x + 3 3x + 3y = 9

Infinitely many solutions.

Step-by-step explanation:

Given

Required

Using substitution method, solve

Substitute -x + 3 for y in

Open bracket

The above shows that there are infinitely many solutions.

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!
