Stella [2.4K]3 years ago
7 0

First:

Subtract 5 on each side of the equals sign to cancel it out. You should get 13x=144.

Next:

Divide 13 from each side of the equals sign to get x by itself.

Answer:

X=11.0769230769. You may need to round it up to 11.08 or 11.1 depending on how your teacher normally has you answer

Answer:

The slopes of line segments AC and AD are same or constant i.e \frac{1}{3}

Step-by-step explanation:

We need to find slopes of AC and AD and tell if they are same or not.

The formula used to calculate slope is: Slope=\frac{y_2-y_1}{x_2-x_1}

Finding slope of AC

We have A=(3,2) and C=(0,1)

Finding slope using formula:

We have x_1=3, y_1=2, x_2=0,y_2=1

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-2}{0-3}\\Slope=\frac{-1}{-3}\\Slope=\frac{1}{3}

So, Slope of AC is \frac{1}{3}

Finding slope of AD

We have A=(3,2) and C=(9,4)

Finding slope using formula:

We have x_1=3, y_1=2, x_2=9,y_2=4

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{4-2}{9-3}\\Slope=\frac{2}{6}\\Slope=\frac{1}{3}

So, Slope of AD is \frac{1}{3}

So, the slopes of line segments AC and AD are same or constant i.e \frac{1}{3}
