1 = 4/r + 4/2r

multiply each side by 2r

2r = 8 +4

2r = 12

r = 6

It takes Julius 6 hours to do the job

It takes Darnell 12 hours to do the job

Write the following equation in slope-intercept form.<br> 3x - 2y=5
prisoha [69]

Answer:

y = 3/2x -5/2

Step-by-step explanation:

Slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

3x- 2y = 5

Solve for y

Subtract 3x from each side

3x -3x- 2y =-3x+ 5

-2y = -3x+5

Divide by -2

-2y/-2 = -3x/-2 +5/-2

y = 3/2x -5/2
