You are looking for a new cell phone plan. the first company, cellular-tastic (f), charges a monthly fee of $35 and $0.11 per minute of use. dirt-cheap cell (g) charges a monthly fee of $55 and $0.01 per minute of use. how many times would you need to use for the cell phones to cost the same amount.

200 minutes

Step-by-step explanation:

Let x minutes is needed to use for the cell phones to coast the same amount.

Now, f(x) = 35 + 0.11x (1) {As per given conditions}

and g(x) = 55 + 0.01 x (2) {As per given conditions}

Now, f(x) = g(x)  

so, 35 + 0.11x = 55 + 0.01x

⇒ 0.1x = 20

⇒ x = 200 minutes.

Therefore, after using 200 minutes the cost of the call will be the same for both the plans. (Answer)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

yes
