I think that each shelf will be 19 inches.  Because 137 divided by 7 is 19 with the remainder of 4.  Half of 4 is 2. Take 2 inches off of each end and that is the 4.  So each shelf is 19 inches.

Answer:

19 inches.

Step-by-step explanation:

We have been given that Michelle has a plank 137 inches long that she wants to cut into 7 shelves of equal length. The plank has jagged ends, so she will start by cutting 2 inches off each end.

Since she cute 2 inches from each end, so she will cut 2*2 inches or 4 inches from both ends.

The length of plank left after cutting off jagged ends would be 137-4=133.

Now, we will divide 133 by 7 to find length of each shelf.

\text{Length of each shelf}=\frac{133\text{ inches}}{7}

\text{Length of each shelf}=19\text{ inches}

Therefore, the length of each shelf would be 19 inches.

What is the value of the function when x =2
Harrizon [31]

Answer:

To make this easier, first draw or imagine a vertical line at x=2

Find where the vertical line and the graph intersects.

Draw or imagine that point of intersection.

Now, draw or imagine a horizontal line that goes through the point of intersection.

That horizontal line tells us the the value of the function by passing through that mark that says "-2"

The function's value at x=2 is -2.

Have an awesome day! :)
