Answer:
see below
Step-by-step explanation:
A relation is "direct variation" if it can be written in the form ...
y = kx
for some constant k. That value can be found from any line* in a table that has direct variation:
k = y/x
_____
* A table with direct variation may have the entry (x, y) = (0, 0). That table entry cannot be used to find the value of k. If either x or y is zero, the other must be also if the variation is <em>direct</em>.
By evaluating the linear function in x = 7 we conclude that:
<em>"The value of f(7) is 6.50, and it represents $6.50 remaining after playing 7 songs."</em>
<h3>
</h3><h3>
Which statement about f(7) is true?</h3>
Here we have the linear function f(x)= 10 - 0.5*x, it represents the amount of money remaining after x songs are played on the jukebox.
Then, that function evaluated in 7 is:
f(7) = 10 - 0.5*7 = 10 - 3.5 = 6.5
This means that after you play 7 songs, the amount of money remaining is $6.5
From this we can see that the correct option is:
<em>"The value of f(7) is 6.50, and it represents $6.50 remaining after playing 7 songs."</em>
