Answer:
D.
Step-by-step explanation:
It would be best to first make sure the line follows the direction of the dots; immediately eliminating B & C.
Then you want to make sure that the estimated line is in the middle and near all of the dots in some way; leaving the final answer, D.
Answer:

Step-by-step explanation:
Given the expression:

We are to find the quotient as shown:

Hence the correct answer is 
Answer:
x = 50°
Step-by-step explanation:
The sum of the measures of the angles of a quadrilateral is 360°
360 - 40 - 80 - 110 = 130
130 is the measure of the quad that is adjacent to the angle of x° and is supplementary to that angle also.
Therefore, x = 180 - 130 = 50
Answer:
It should be C
Step-by-step explanation:
Substituting in a value of x,
4 * ( 1/2 )^x 4 * ( 1/2 )^x
= 4 * ( 1/2 )^ 2 = 4 * ( 1/2 )^ -2
= 4 * 1/4 = 4 * 4
= 1 = 16
C checks out, and all the other options don't equal to the values on the table.
