Answer:
r=-11
Step-by-step explanation:
X^2-18 = 3x
x^2 - 3x - 18 = 0
(x-6)(x+3) = 0
x = {-3,6}
So -3 is the answer
5(n+6)=48
5n+30=48
5n=18
n=18/5
Answer:
Yes, it is a function
Step-by-step explanation:
A function is a set of ordered pairs where there is no two of the same domain. The domain is the first coordinate which is x. In this case, the x coordinates are 4, 0, 11, 17. There is no two of the same domain so this is a function.
