Since DC = 12, then EF also = 12.

Both AD and BC are indicated to be the same .

So AE = (24 - 12) / 2 = 12/2 = 6

Now you have a right triangle with height DE = 8 and base AE = 6

Using the Pythagorean Theorem we can now find AD:

AD = √(8^2 + 6^2)

AD = √(64 + 36)

AD =√100

AD = 10

Find the inequality represented by the graph.

Simora [160]

Answer:

y < $\frac{3}{4}$ x

Step-by-step explanation:

Since the line is dotted and shaded down that mean the sign is <.

The slope is rise over run or 3/4.

Since the line intercepts the y-intercept at (0,0) that means that the y-int is 0

So the full equation is y < 3/4 x

serg [7]

Answer:

x = 11

Step-by-step explanation:

JM = JK + KL + LM

<u>Substitute the values and solve for x:</u>

23 = 9 + 2x - 18 + x - 1
23 = 3x - 10
3x = 23 + 10
3x = 33
x = 33/3
x = 11
