15x + 3y = 27
a. (0,9)
b. (1,4)
c. No solution
d. Infinite solutions

Answers

Answer:

D. Infinite solutions.

Step-by-step explanation:

Since they give us the equation for (y) we just implement that equation in place of (y) in the second equation

15x+3y=27 now becomes

15x+3(-5x+9)=27

Distribute the 3

15x-15x+27=27

15x and -15x cancel out

27=27

Infinite solutions since both sides are exactly equal.

Answer:

A: 30

Step-by-step explanation:

Actually, I think the answer is the last one, because it asks for the answer to the angle ACD. Basically, you can solve this two ways: add 33 and 117 or to double check, add 33 and 117 and subtract the answer from 180, the answer would be 30 for the angle ACB, then subtract 30 from 180, your answer is 150.
