Question

MEDAL AND FAN
The equation below shows the perimeter f(x) of several rectangular side tables having width x inches:
f(x) = 24 + 2x
The perimeter of each table is less than 50 inches. Which of the following best describes the domain of f(x)?
A)All integers greater than 0 and less than 13
B) All integers greater than 0 and less than 50
C) All real numbers greater than 0 and less than 13
D) All real numbers greater than 0 and less than 50

Answer 1

f(x) <=50
f(x) = 24 + 2x
50 = 24 + 2x
-24 -24
26=2x
26/2 2x/2
13=x

Answer 2

That is what I have so far @misty1212 could you help me please?

Answer 3

I know its not B or D

Answer 4

Im thinking A

Answer 5

i think you did it only the inequality became an equal sign

Answer 6

oh oops

Answer 7

So it is A? I got it right?

Answer 8

greater than zero, less than 13 right?

Answer 9

Yes integers correct?

Answer 10

no i don't think they have to be integers

Answer 11

then could be fractions too

Answer 12

pick C
C) All real numbers greater than 0 and less than 13

Answer 13

I would think it would be A or C integers or Real numbers but I chose integers based on the theory it could be anything

Answer 14

Okies :3 Thankies!

Answer 15

one side could be \(10.5\) or some other number that is not an integer

Answer 16

welkies (?)

Answer 17

Thats true.

Answer 18

my view on it is A doesnt say it is only integers but says it accepts all integers between those numbers

Answer 19

But I agree with you
