The first three steps in determining the solution set of the system of equations, y = –x2 – 2x + 8 and y = 2x + 11, algebraically are shown in the table. which represents the solution(s) of this system of equations?

All three of the steps shown are correct. Finish the solution by solving

0 = (x+1)(x+3). The solutions are x= -1 and x = -3.

Now subst. -3 for x in either of the given equations, to find the corresponding y.

Next, subst. -1 for x in either of the given equations, to find the corresponding y.

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

answer:

your answer is: c. 196 7/8 in^3.
