This is actually called a mapping diagram but the answer is C.
Because the right circle represents the x variable and the left circle is the y variable. So you just follow the arrows. -3 is pointing to 4 so that's a pair or (-3,4)

Answer:
A) 30 and 60
Step-by-step explanation:
Complimentary angles combined = 90°.
One of the angles is twice the other. Let the measurement of the smaller one = x. Set the equation:
x + (2x) = 90°
Simplify. Combine like terms:
(x + 2x) = 90
3x = 90
Isolate the variable, x. Divide 3 from both sides:
(3x)/3 = (90)/3
x = 90/3
x = 30
Find the other measurement. The other measurement is twice the size of the first one. Multiply the number gotten by 2:
2(x) = 2(30) = 60
A) 30 and 60 is your answer.
