Step-by-step explanation:
x= new books
y= old books
(to help keep track)
12.50x + 5.50y or 12.50(16) + 5.50(25)
so 337.50 in revenue
The correct answer for this question is this one: "<span>y = -x + 2"</span>
<span> y - intercept = (0,2) slope = -1
y = mx + b
2 = -1 (0) + b
b = 2
so the equation of the line is
<u>y = -x + 2</u></span>
Hope this helps answer your question and have a nice day ahead.
Answer:

Step-by-step explanation:
We have the following function
y = 12^x, and we need to find the inverse function.
To find the inverse function we should solve the equation for "x". To do so, first, we need to:
1. Take the logarithm in both sides of the equation:
lg_12 (y) = log _12 (12^x)
(Please read lg_12 as: "Logarithm with base 12")
From property of logarithm, we know that lg (a^b) = b*log(a)
Then:
lg_12 (y) = x*log _12 (12)
We also know that log _12 (12) = 1
Then:
x = log_12(y).
Then, the inverse of: y= 12^x is:

93,000 is the correct answer
