Ok, so the function form is y = a * bx.
Substitute in the values:
750 = a * b5
and
48 = a * b2
Then divide the two equations:
750/ 48 = (a * b5) / (a * b2)
So:
15.625 = b3
Take the cube root of both sides:
2.5 = b
Now, substitue b into one of the equations (the one with 48 has smaller numbers and is easier to work with.)
48 = a * 2.52
Simplify.
48 = a * 6.25
Divide both sides by 6.25
7.68 = a
Now substitute in a and b to write the exponential function:
y = 7.68 * 2.5x
The prime factors are: 2 x 2 x 2 x 2 x 2 x 3 x 5
Answer:
5 games
Step-by-step explanation:
So basically if she has 13 books and 8 more books than games.
She has more books than games right.
So you just subtract 13 from 8 to get your 5 games.
