2) Rearrange the formula: KE= 1/2mv . Solve for m
A. M= 2v2/KE C. M= v2/ 2KE
B. M=KE/2v2 D. M=2KE/v2

Answer 1

the answer is d i took the test

Explanation:

Answer 2

The answer is B

Explanation:

Problem 1

Step 1 write the equation

Step 2 what you do to one side you have to do to the other side. + 8x to both sides.

Step 3 Divide by 4 on both sides. Answer for that would be 4y=20/4+8x/4

Step 4 y=5+2x

problem 2

I cant do sorry
