The simplified expression is 6+3i
Answer: B. Linear
Step-by-step explanation: Y: -5, -1, 1, 3, 7
X: -3, -1, 0, 1, 3
Ok, when you are doing a problem like this you are going to have to line you X and Y's up from least to greatest. Then, you will look at the X and see if any of the X values repeat. If any of your X values repeat, then they are "Non-Linear." If they do not repeat, then that means they are "Linear."
Answer:

Step-by-step explanation:

First, we multiply both fractions by 8:

Simplify:

The radius of the circle is 81.78
Answer:
m∠SQR = 74°
Step-by-step explanation:
Points P, Q and R are collinear.
Therefore, angles PQR and angle RQS are the linear pair of angles.
Since linear pair of angles are supplementary angles.
m∠PQR + m∠RQS = 180°
By substituting the measures of the given angles,
(3m + 1) + (2m + 4) = 180
5m + 5 = 180
5m = 180 - 5
5m = 175
m = 
m = 35
Since, m∠SQR = (2m + 4)°
= (2×35) + 4
= 74°
Therefore, m∠SQR = 74° is the answer.
