Answer:

D: {-4, -1, 4}

R: {0, 2}

Step-by-step explanation:

The domain of a relationship is the possible values of x. On the other hand, the range is the possible values of y. To write out the domain and range of a discrete relationship simply write the given x and y values. The x values are -4, -1, and 4. Set notation is written least to greatest and uses brackets, so the domain is {-4, -1, 4}. Do the same for the range and remember that numbers should not repeat in set notation. This gives you {0, 2}.

Answer:

12.5

Step-by-step explanation:

Step 1:

0.4 ( 3b + 10 ) = 19 Equation

Step 2:

1.2b + 4 = 19 Multiply

Step 3:

1.2b = 15 Subtract 4 on both sides

Step 4:

15 ÷ 1.2 Divide

Answer:

b = 12.5

Given:

AD is an angle bisector in triangle ABC. $m\angle CAB=44^\circ, m\angle ACB=72^\circ, m\angle ABC=64^\circ$ .

To find:

The value of $m\angle ADC$ .

Solution:

AD is an angle bisector in triangle ABC.

$m\angle CAD=m\angle BAD=\dfrac{m\angle CAB}{2}$

$m\angle CAD=m\angle BAD=\dfrac{44^\circ}{2}$

$m\angle CAD=m\angle BAD=22^\circ$

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.

Using angle sum property in triangle CAD, we get

$m\angle CAD+m\angle ADC+m\angle ACB=180^\circ$

$22^\circ+m\angle ADC+72^\circ=180^\circ$

$m\angle ADC+94^\circ=180^\circ$

$m\angle ADC=180^\circ-94^\circ$

$m\angle ADC=86^\circ$

Therefore, the angle of angle ADC is $86^\circ$ .

C < 5

there will be an open circle on 5....it is open because there is no equal sign in the problem.....the shading will be to the left....because less then is shaded to the left
