99 boys was survey. for every 4 boys that like soccer 5 boys like basketball. how many students enjoy basketball and how many enjoy soccer?

44 soccer, and 55 basketball.

Step-by-step explanation: This is one method that I used: Round up to 100 boys. Add a 0 to both 4 and 5, leaving 40 and 50. Add 5 to each one since it is 100, leaving 45 and 55. Since it still has to be 99 and soccer is lesser, take 1 away from 45 leaving 44 soccer and 55 basketball players.

y= 10(4^x)

Step-by-step explanation:

First, plug in (0,10) to the equation. 10=a*(b^0), since any number to the 0th power equals 1, 10=a*1, or 10=a.

Now, plug in (2,160) to y=10*b^x, or 160=10*b^2. Dividing by 10, 16=b^2, taking the square root, 4=b.

So, 10=a and 4=b, putting those in the equation. y=10(4^x).
