3/2 x - 5/4 y =15 rate of change​
Alenkinab [10]

Answer:

6/5

Step-by-step explanation:

m is your rate of change you need to get y by itself.

3/2x - 15 = 5/4y

3x/2 - 30/2 = 5/4y

3x-30/2 = 5/4y

3x - 30 = 2 x 5/4y

3x - 30 = 2 x 5/4x2y (cross out 2 and 4)

3x - 30 = 5/2y

2 x 3x - 2 x 30 = 2 x 5/4y

6x - 60 = 5y

6x/5 - 60/5 = 5y/5

y = 6/5 x x - 12

Which of the following choices shows the proper use of the distributive property?
lianna [129]

Answer:

-2(6x - y)  = -12x +2y

Step-by-step explanation:

Required

Which shows distributive property

Distributive property states that:

a(b + c) = a * b + a * c

So, the solution to -2(6x - y) is:

-2(6x - y)

Open bracket

-2(6x - y)  = -2 * 6x -2 *-y

-2(6x - y)  = -12x +2y

(a) is true
