Hello from MrBillDoesMath!
Answer:
My interpretation of f(x) is f(x) = (1/6x) + 2
Domain = {Real Numbers} - {0}
Range = {Real Numbers}
Discussion:
Domain of f = all x where f(x) is defined. For f(x) the only singularity occurs at x = 0 so the domain is the set of all real numbers except for 0. For x>0, x values close to 0 cause y to grow large while large x causes y to approach 0. A similar argument for x <0 shows that the range of f is all real numbers.
Thank you,
MrB
Answer:
18
Step-by-step explanation:
When you do subtraction and addition you do it from left to right. So I did 16-3 which is 13, and I did 13+5 which is 18.
Cheers,

Answer:
r=6
Step-by-step explanation:
6/11=r/11
cross product
11*r=6*11
11r=66
r=66/11
r=6
Let notebooks be x and let pencils be y
4x+9y=8.25 (equation 1)
7x+14y=14.00 (equation 2)
Multiply equation 1 by 7
So that you get 28x+63y=57.75
Multiply equation 2 by 4
So that you get 28x+56y=56.00
28x+63y=57.75 -
28x+56y=56.00
-----------------------
7y=1.75
Divide both sides by 7
1.75/7 is 0.25
So, now we know that one pencil costs 0.25 cents
Sub this y value into equation one
4x+9(0.25)=8.25
4x+2.25=8.25
Move 2.25 to the other side as a negative number
4x= 6
Divide both sides by 4
6/4 is $1.50
So, one pencil is equal to 0.25 cents and one notebook is equal to $1.50
