A family plan for a cell phone has a monthly base price of $75 plus $10.99 for each additional family member added beyond the pr
imary account holder. The linear function to model the monthly cost C(x) (in $) of a family for x additional family members added is C(x)=
1 answer:
The linear equation that models the cost for having x additional family members added is:
c(x) = $75 + $10.99*x
<h3>
How to get the linear equation?</h3>
Here we know that the plan has a fixed price of $75 plus $10.99 for each family member added beyond the primary account holder.
Then if there are x family members added, the cost will be:
$75 + $10.99*x
Then the linear equation that models the cost for having x additional family members added is:
c(x) = $75 + $10.99*x

Negative times a negative equals a positive
The slope is -3/1 so to find other points, go to (2,-1) and go down 3, over 1.
Answer:
the first one must be 39.5 and the other 42.5
Step-by-step explanation:
multiply 35 by 6 and subtract 32 x 4 you are left with 82. Divide that by 2 and make the difference 3.
Length(l)= 4+ w
Width(w)=w
Area(A)= 21m^2
so keep in mind Area= Length × width
A= l×w
21=(4+w)(w)
21= 4w+ 2w
21=6w
w=3.5
The width is 3.5m
so the answer is about 4m
