Answer:
c = 4x + 35
Step-by-step explanation:
Imagine c = cost
$35 is base price so you add that to whatever else you spend.
Let x = number of channels you buy. ($4/CHANNEL)
so cost is equal to $4*channels plus 35
Therefore
c = 4x+35
should be
<em>c = 4p + 35</em>
cause you pay 35 as a standard and then you just multiply 4 with the number of extra channels.
Using the distance formula, we see that the distance between (-4,4) and (-7,3) is .
c is the one with function
