The Varials x and Y are directly proportional and Y=4 when x=9 . What is the value of Y when x=18

Y= 8.

Step-by-step explanation:

If they are directly proportional, we can set up two fractions like this:

We can solve for Y by multiplying both sides by 18, giving us:

Y= 8.

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
