  1. L×W=15 or 5×3=15
  2. 15×H=60 or 15×4=60
  3. 60÷3=20 in cubed

Therefore V =20 in cubed

Find the x-intercept of the line 3x - 9y = 15.
erastovalidia [21]

Answer:

The x-intercept is 5.

Some people prefer you right it as a point (5,0).

Step-by-step explanation:

The x-intercept can be found by setting y=0 and solving for x.

Just like to find the y-intercept you can set x=0 and solve for y.

Let's find the x-intercept.

So we will set y=0 and solve for x:

3x-9y=15

3x-9(0)=15

3x-0    =15

3x        =15

Divide both sides by 3:

 x         =15/3

 x          =5

So the x-intercept is (5,0).
