If u are 4/7 mile from your home and u can walk 4 5/7 miles per hour , how long will it take for u to walk to your home a) 4/33 hour b) 80/49 hours c) 20/231 hour d) 80/49 hours e) 132/49 hours which one is the best answer ..

A) 4/33 hour

Step-by-step explanation:

This is a distance = rate * time problem

We are given the distance and the rate, now we need to solve for the time:

Let's change that mixed fraction into an improper one:

Now to solve for t we can multiply the 33/7  by its recirocal:

Multiplying a fraction by its reciprocal = 1, so that leaves only a t on the right:

The 7's cancel out on the left and that leaves you with

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
