Which equation shows y=3x−15 in standard form?
15x+y=-1
15x-5=1
5x-15y=1
5x-15y=-1

the correct answer would be I think 5x-15y=1

Step-by-step explanation:

I have already learned that

it's 5x - 15y = 1

Step-by-step explanation:

Hope this helped have a wonderful day!!! :)

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
