A solution is when the two lines intersect, when they have the same (x,y) point.  So we can say y=y which is the same as saying:

2x-15=5x

-3x-15=0

-3x=15

x=-5, now use either to solve for the y coordinate...y=5x becomes:

y=5(-5)=-25 so the solution is the point:

(-5, -25)

We start with:

y=2x-15
y=5x

Now, we have a perfectly set-up variable we can get rid of: <em>y.</em>

But we need to make either the top or bottom equation negative, so for simplicity, let's make the bottom one negative.

y=2x-15
(-y)=(-5x)

Now simplify.

-3x-15=0

Add 3x on both sides.

3x=15

Divide by 3 on both sides.

x=5

Sorry I also need help with this question
Tomtit [17]

Answer: B

Step-by-step explanation:

(f/g) means to divide f(x) by g(x).

(f/g)(x)=\frac{3x+2}{3x-5}

To find the domain, you set the domain equal to zero and solve for x.

3x-5=0                   [add both sides by 5]

3x=5                       [divide both sides by 3]

x=5/3

Now, we know that B is the correct answer.
