Answer=15X
$45/3 hours = $15/hour
(b) To see how much Louis makes per hour, simply plug in 1 for the hours value x:
y = 12(1 hours)
y = $12/hour
Thus Carl makes more than Louis.
(c) The equation of Carl's dollars per hour is similar to Louis':
Answer:
10 pillowcases
Step-by-step explanation:
It will take 8 seconds for all of the dominoes to fall over.
This will be an exponential function. To find the growth rate, we can write out the terms of the sequence that goes along with it: 10, 20, 40, ...
"Growth rate" is the same as percent of increase or decrease. We find the amount of increase and divide by the original amount: 20-10 = 10 increase; 10/10 = 1.
The exponential function is of the form
f(x) = a*(1+r)ˣ, where a is the initial value (10), r is the growth rate (1), and x is the number of time periods. Using the variables given to us in the problem along with this information, we have:

Divide both sides by 10:

We will use logarithms to solve this:

The line crosses the x -axis at point (9,0) and the y-axis at point (0,6).
If the equation of the line is
then substitute the coordinates of the points into this equation:
1) 
2) 
Substitute the second equation into the first:

The equation of the line is
