What would be the most appropriate first step if you wanted to solve this system of equations using elimination? 3x+2y=7 x+4y=−8 A. Multiply the first equation by −1 B. Multiply the second equation by −2 C. Multiply the first equation by −2 D. Multiply the second equation by -1−1

A. Multiply the first equation by −1

Step-by-step explanation:

From the above question, our system of equations is

3x+2y=7... Equation 1

x+4y=−8 Equation 2

Hence, solving by Elimination, the first step would be if we are eliminating x first, we are to Multiply Equation 1 by -1

Option A is the correct option

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
