Answer:
non- function
Step-by-step explanation:
any X being REPEATED (the first number of each pair) is non-function.
=40mn-12m+40mn-9mn+6n-24m+72mn-5mn-36mn
=102mn-36m+6n
Answer:
B (for question 7)
Step-by-step explanation:
To find the slope, we use the equation
.
m = (-4+1)/(7+2) = -3/9 = -1/3
Since B is the only option that would give a slope of -1/3, B must be the answer.
(you can use this same method for question 8)
Answer:
yields zero
Step-by-step explanation:
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero.
