Ireally need 1) solve this equation for y: -8x+4y=20 a. y= 2x- 5 c. y=1/2 = 5 b. y= 2x +5 d. y= 1/2x +20 2 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

The answer is B

Step-by-step 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

the answer is d i took the test

Step-by-step explanation:

y=x+2 hope this jdjxhdnzbdjdo

what is the answer?
