Answer: 6

Since one of the points is at the origin, then you can take the number point on the x axis and multiply it by the point on the y axis, and you get 12. To find the area of a triangle, you must use base x height divided by 2. Divide 12 by 2 to get 6.

Answer:

The total volume of the whole figure is 576m³.

Step-by-step explanation:

First find the volume for the first figure.

Volume of a Rectangular Prism (formula): L•W•H

V = (15m)(12m)(2m)

V = 360m³

Now, find the volume for the second figure.

V = (6m)(12m)(3m)

V = 216m³

Finally, just add both volumes to find the total volume of the entire figure.

Vt = 216m³ + 360m³

Vt = 576m³

Solve for x (get x by itself)


4x-\frac{5}{y} =2z       Add 5/y on both sides

4x-\frac{5}{y}+\frac{5}{y}=2z+\frac{5}{y}

4x=2z+\frac{5}{y}       Divide 4 on both sides to get "x" by itself

\frac{4x}{4} =\frac{2z+\frac{5}{y}}{4}

x = \frac{z}{2}+\frac{5}{4y}



If dividing 4 confuses you, then you can do this:

4x=2z+\frac{5}{y}      Multiply 1/4 on both sides

(\frac{1}{4})4x=(2z+\frac{5}{y})(\frac{1}{4})  Distribute 1/4 into (2z + 5/y)

x=(2z(\frac{1}{4})+\frac{5}{y}(\frac{1}{4}))

x = \frac{z}{2} +\frac{5}{4y}

Y intercept <br> x intercept<br> and the slope
masha68 [24]

Answer:

y-intercept = (0, - 3)

x-intercept = (-6, 0)

slope = - 1/2

Step-by-step explanation:

The y intercept is the value of y when the x = 0. By looking at the graph, we can tell that when x = 0, y = - 3. Likewise for the x-intercept.

We can use the slope formula to determine the slope.

m = y2 - y1/ x2 - x1

You can choose any 2 points on the line and substitute in the formula. I chose the y and x intercepts for easier calculations.

m = - 3 - 0/ 0 - (- 6)

m = - 3/ 6

m = - 1/2
