It is B because if you use guess and check plug in 0 for all equations and only B matches with the function.
Answer:
50<x<60
Step-by-step explanation:
The triangle can only be formed with these two side lengths if the third side is bigger than (Subtract them)
55 - 5
...and smaller than (Add them)
55 + 5
55-5 < x < 55+5
50 < x < 60
Answer:
C) C(x) = 5 +0.25x
Step-by-step explanation:
Let
C(x) ---> the total cost monthly
x ---> is the number of hours in a month
we know that
he linear equation in slope intercept form is given by
![C(x)=mx+b](https://tex.z-dn.net/?f=C%28x%29%3Dmx%2Bb)
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
The slope is equal to
![m=\$0.25\ per\ hour](https://tex.z-dn.net/?f=m%3D%5C%240.25%5C%20per%5C%20hour)
The initial value or y-intercept is equal to
![b=\$5.00](https://tex.z-dn.net/?f=b%3D%5C%245.00)
substitute
![C(x)=0.25x+5.00](https://tex.z-dn.net/?f=C%28x%29%3D0.25x%2B5.00)
