Answer:
144
Step-by-step explanation:
Ok, we know the angle is 3π/4, and that y-coordinate is 1, hmm what's "x"?
the answer is 1,576,800,000
Problem 4:
4a = -15
4b = -75
4c = 125
Problem 5:
5a = -5
5b = 95
5c = -19 
Step-by-step explanation:
<em> See attached for my work. </em>
For problem 4, we substitute the different values given for x and solve.
For problem 5, we set the function equal to the given values and solve.
