Set up the ratios as proportional fractions:

We can simplify the first fraction to make the problem easier. Both the numerator and denominator of the first fraction can be divided by 3:


Both fractions now have the same denominator. Since both fractions have to equal each other, the numerators will also be the same. Therefore,
x = 4.
A linear function means you’re working with a line. Lines can be stated in slope-intercept form: y=mx+b.
To make it a linear function, you simply replace “y” with “f(x)” notation: f(x) = mx + b
The information you gave told you m=2 and b=6, since (0,b) is the y-intercept.
Putting that all together you have:
f(x) = 2x + 6
Answer:
Only
is a perfect cube.
Step-by-step explanation:
is not a perfect cube because 8 is not a multiple of 3.
Now,
is a perfect cube since 24 is a multiple of 3.
So,
can be expressed as
Again,
is not a perfect cube as 28 is not a multiple of 3.
And also
is not a perfect cube as 64 is not a multiple of 3.
Therefore, only
is a perfect cube. (Answer)
