What is the solution to the system of equations?
10x+3y=43
-9x-y=-20
(11, 1)
(1, 11)
(–1, 11)
(11, –1)

(1, 11)

Step-by-step explanation:

If you plug  both of these values in for the x and y in both equations you will get a true statement.

10(1) + 3(11) = 43

10 + 33 = 43

-9(1) - (11) = -20

-9 - 11 = -20

i will pick c put check it over to be sure

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
