I need a complete answer for the entire thing (Please Help)

14 1/2

Step-by-step explanation:

Ok let's get started!

First things first...

Let's see what information we have!

Monday practice: 2 1/2 hours

Tuesday practice: 1 3/4 hours

Wednesday practice: 3 hours

First Step:

We need to put each fraction in improper form, so now it will look like this:

Monday practice: 5 / 2 hours

Tuesday practice: 7 / 4 hours

Wednesday practice: 12 / 4 hours

Now why did I put the Wednesday practice in terms of 4? Because we need to find a common denominator and that will be 4 so I made life easier and did it ahead of time!

Second Step:

We now need to put the Monday practice hours with a denominator of 4.

So we need to multiply the denominator by 4 and will do the same for the numerator so now we get:

5*2 / 2*2

Which is 10 / 4!

(hour)

Third Step:

Now we need to add a weeks worth of practice!

10 / 4  +  7 / 4  +  12 / 4 =  29 / 4

So, in a week Cory practices 29 / 4 hours, that's a lot!

Fourth Step:

Now we must find how much she does in 2 weeks. To do so we will do something a little more different then usual. We are going to put 29 / 4 in mixed number form. We will get 7  1/4.

Fifth Step:

Last step!

We will multiply 7 and 1/4 by 2,

7*2 and 1 / 4*2 =

14 and 2 / 4

Now we can still simplify 2 / 4 down to 1 / 2.

So our answer is

14 1/2

Sixth Step:

I lied there is one more step

REJOICE

We got through the math problem WHOOP! WHOOP!

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
