How to solve systems of equations by graphing

Mathematics

In order to solve system by graphing, you first need to write each equation in slope-intercept form or y = mx + b form.

In this form, y is isolated on the left side of the equation.

In some problems, this will already be done for you.

After that, graph both lines on a coordinate system.

What you are looking for is the point where the lines intersect.

That point will represent the x and y that is the solution.

Feel free to plot many points along the line.

Answer:

The surface area of the triangular prism is 84 square centimeters.

Step-by-step explanation:

The surface area of a figure is exactly what it means, the area of its outer surface or the added areas of each face that makes the figure.

Nets are a way to find surface area easier because it is an outline of the faces of the 3d figure.

But since we don’t have a net, we will just find the area of each face that forms this right triangular prism:

The two congruent triangular bases:

1/2 x 4 x 3 = 6 cm^2

6 x 2 = 12 cm^2

Lateral bottom rectangular face:

6 x 3 = 18 cm^2

Lateral to the right rectangular face:

5 x 6 = 30 cm^2

Lateral to the left rectangular face:

4 x 6 = 24 cm^2

Add up all the values:

12 + 18 + 30 + 24 = 84

The SA is 84 square centimeters
