Answer:
B (12)
Step-by-step explanation:
The expression can be written as the following:
(2n)(n-1)
Let n=3
(2*3)(3-1)=(6)(2)=12
So the answer is B (12).
The first relation gives two y-values for any given x-value (except x=6).
y² +x = 6 . . . . . is not a function
-2x+3=15
Subtract 3 from both sides:
-2x=12
Divide -2 from both sides:
X=-16 is your answer
Answer:
x>-1
Step-by-step explanation:
Subtract 0.7 from both sides
