Answer:
<em>The greatest number of song he can practice in a week is 2.</em>
Step-by-step explanation:
Suppose, the greatest number of song he can practice in a week is 
He practices each song for
hours. So, the total time required for practicing
number of songs
hours.
Given that, he practices his guitar for 9 hours each week.
So, the equation will be......

<em>(Rounded as the greatest whole number)</em>
Thus, the greatest number of song he can practice in a week is 2.
Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
Find the domain of g(y), and this will be the range of f(x). ...
If you can't seem to solve for x, then try graphing the function to find the range.
Answer:

Step-by-step explanation:
The slope of the line joining the 2 points is a measure of the average rate of change.
Calculate slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (- 3, - 2)
m =
=
=
← average rate of change
Answer: I wouldn’t be able to make a linear system right now, but it would be better to use Hamster Fun if it were long-term, and Hamster Heaven if it were short-term.
Step-by-step explanation:
HH (Hamster Heaven) charges 20$ plus one a day, and HF (the other) charges 35 plus one a day, so if you went for 80 days for either one:
HH: 20 + (2.50 x 80) =
20+200: 220
HF: 35 + (1 x 80)= 115
If it were for only a day or two, it would be more efficient to use Hamster Heaven.
