answer is D.
Answer:
domain: {2, -1, 5, -3}
range: {2, 4, 2, 0}
Step-by-step explanation:
domain : of all the input values shown on the x-axis.
range : the set of possible output values shown on the y-axis.
Simple interest formula:

where

=interest,

=principal (how much you put in at first),

=rate as a decimal, and

=number of years.
Let's plug in what we're given.

Calculate it out...

The interest earned is $70.00.
(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.
180-x-180+2x=53
x=53
Final answer: The angle is 53 degrees.
