Answer:
Neither A or B
Step-by-step explanation:
Hello There!
In order for a set of ordered pairs to represent a function none of the x values can repeat
In answer choice A the x value 7 repeats therefore the set of ordered pairs do not represent a function
In answer choice B the x value 7 repeats therefore the set of ordered pairs do not represent a function
so we can conclude that neither set of ordered pairs represent a function
What changes about the numbers when you go from one to the next, and what stays the same? Here, it looks like you start with the number 44, but how do you change the number from one to the next?
Answer:
Line 1
Step-by-step explanation:
Since x=3 and y=-6, just plug those two values in both of the equations.
Line1: (3)-(-6)=9 This would be the answer
Line2: 3(3)+3(-6) = -9 This is the incorrect answer because it should 3
Answer:
30

Exterior angle equals sum of opposite interior angles
3x = 2x + 30
3x - 2x = 30
x = 30
