The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 350
minutes, the monthly cost will be $137. If the customer uses 900 minutes, the monthly cost will be
$302.
A) Find an equation in the form y = mx + b, where x is the number of monthly minutes used and
y is the total monthly cost of the Ringular plan.
Answer y =
B) Use your equation to find the total monthly cost if 830 minutes are used.
If 830 minutes are used, the total cost will be
dollars.

step-by-step explanation:

plese mark mde brainliest!

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

asnwer is (g o h o f)(x) = 2x - 6/x + 7

step-by-step explanation:

given,

f(x) = x - 3/x

g(x) = x + 3

h(x) = 2x + 1

we need to find : (g o h o f)(x)

we can write (g o h o f)(x) = g[ h{ f(x) } ]

so first we find h{f(x)}

h{f(x)} = f(x) + 3 = (x - 3/x) + 3

h{f(x)} = x - 3/x + 3

now we find g[ h{ f(x) } ].

g[ h{ f(x) } ] = g(x - 3/x + 3)       {plug h{f(x)} = x - 3/x + 3 in g[h{f(x)}] }

g(x - 3/x + 3) = 2 (x - 3/x + 3) + 1

                    = 2x - 6/x + 6 + 1

                    = 2x - 6/x + 7

hence we get (g o h o f)(x) = 2x - 6/x + 7

c and d is your answers.
