Answer:
the measure of the exterior angle is 87 degrees.
To be a function each different x value would have a different Y value.
First one is a function, there are no repeated Y values.
The second one is a function.
Third one is not a function because it has two identical Y values with different x values.
The fourth one is a function.
Answer:
10/8 = 5/4x
y=5/4x
hope that answers your question
Step-by-step explanation:
-2 < -3 (I think so anyway)
Answer: x=68/11 and y=-72/11
Steps:
2(x+4y=-20)
2x+8y=-40
2x - 3y = 32
- 2x + 8y = -40
-11y=72
y=-72/11
x + 4(-72/11) = -20
x - 288/11 = -20
x=68/11
