Answer:

Initial amount: 20

Growth factor: The amount doubles for every integer increase of x

Step-by-step explanation:

I think the equation should be g(x) = 20(2^x) for it to be exponential.

The general form of an exponential equation is g(x) = a(b^x), where a is the initial amount when x = 0, and b is the base, or growth factor.

We can see the amount double by evaluating a few value..

g(0) = 20(2^0) = 20(1) = 20   (initial amount)

g(1) = 20(2^1)  =  20(2) = 40

g(2) = 20(2^2) = 20(4) = 80

g(3) = 20(2^3) = 20(8) = 160

This pattern will continue on

How many solutions does the equation -4y + 4y + 2=2
Luden [163]

Answer:

Infinite Solutions

Step-by-step explanation:

If you look at the equation careful you will see this part "-4y+4y".  If you see that the variables cancel each other out leaving 2=2.  That means that for any value of y, 2=2.  Because the variable cancels itself out it doesn't mater what the variable is.  So there is an infinite amount of values you can have for "y".

LuckyWell [14K]

Answer:

x+y=24 so we can say

x=24-y making 3x+5y=100 become

3(24-y)+5y=100

72-3y+5y=100

72+2y=100

2y=28

y=14, since x=24-y

x=10

So there are 10 3-point questions and 14 5-point questions.
