Question

u y is directly proportional to the square root of x Given that y=12 when x 36 find (a) the formula for y in terms of t. (b) the value of when yo 10.​

Answer 1

Answer:

Y is directly proportional to x, and y = 24 when x = 4. What is the value of y when x = 3?

Let’s assume Y=y and autocorrect capitalized it for you.

If y is directly proportional to x, then there exists some constant, k, such that y =kx

given

y= 24 when x = 4

24 = k*4

6 = k

so y = 6x

find y if x=3

y= 6*3

y=18
