Just move over the two. When you change to standard form you want the x and y together and the constant by itself.

7x-4y+2=0
7x-4y+2-2=0-2
7x-4y=-2


Standard form: 7x-4y=-2

If m proportional to n and m=5 when n=4.what is the valuue of m?when n=18
Dovator [93]

Answer:

m=22.5

Step-by-step explanation:

m is proportional to n means there is some constant k such that:

m=kn

If m=5 when n=4 then we have the following equation to solve for our constant k:

5=k(4)

5=4k

Divide both sides by 4:

5/4 =k

So k=5/4 no matter what (m,n) pair they give you where the equation is m=kn.

m=(5/4)n

What is m when n=18?

m=(5/4)(18)

m=(5/2)(9)

m=45/2

m=22.5
