schepotkina [342]

Answer:

-9/7

Step-by-step

Slope Formula:

$\frac{y_2-y_1}{x_2-x_1}$

We can plug in the numbers 7 and -2 for the y and -4 and 3 for x

$\frac{7-(-2)}{-4-3} =\frac{9}{-7}$

The volume of a right triangular prism is 72 cubic feet. The height of the prism is 9 feet. The triangular base is an isosceles

Maslowich

Answer:

<h2>The area of the triangular base = 8 ft²</h2>

Step-by-step explanation:

The formula of a volume of a prism:

$V=A_BH$

$A_B-area\ of\ a\ base\\H-height$

We have

$V=72\ ft^3,\ H=9\ ft$

Substitute:

$72=9A_B$ <em>divide both sides by 9</em>

$8=A_B\to A_B=8\ ft^2$

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).
