The function C(x) = 29x + 54.5 represents the cost (in dollars) of cable for x months, including $54.50 installation fee. How ma
ny months of cable service can you have for $344.50?

1 answer:
Hey there!!
Given equation :
... c(x) = 29x + 54.5
<em>In this equation $54.50 is installation fee and this would remain as a constant. ( This value wouldn't change ). </em>
<em>'x' is represented as the number of months. </em>
The total cost or c(x) is given as $344.50
Getting this into equations :
... 344.50 = 29x + 54.5
Subtracting 54.5 on both sides :
... 29x = 290
Dividing by 29 on both sides :
... x = 10
<u><em>Hence, the number of months is 10. </em></u>
Hope my answer helps!!

Answer:
=20.5
Step-by-step explanation:
1. use the Pythagorean theorem: a^2+ b^2=c^2 (arms+legs squared=hypotenuse)
2. plug in the numbers to the equation:
14^2+15^2=c
225+196=c^2
421=C^2
the square root of 421 is 20.5 which is the hypotenuse of the triangle
5 goes into both 15 and 40, so you'd divide each by that, which would leave you with 3/8 (three eighths) as the simplest form.
0, No solution.
-4x-11=2 (x-3x)+13
-4x-11=2 (-2x)+13
-4x-11=-4x+13
-11 is not equal to 13 so there is no solution
