Drag the tiles to the table. The tiles can be used more than once, but not all tiles will be used. Emma and Jackson are helping their band raise funds for a trip to New York City. They've volunteered to call every
business owner in their small town to request donations. Emma can complete the calls in 6 days if she works alone.
Jackson can complete the calls in 4 days if he works alone. To complete the task, Emma and Jackson are going to work
together for the same amount of time. Use this information to complete the table.

Emma can complete the calls alone in 6 days, which means she can complete   of the calls in one day. So, Emma’s rate per day is . Jackson can complete the calls alone in days, which means he can complete of the calls in one day. So, Jackson’s rate per day is . Because they’re working together, the time, , is the same for both.

Multiply across the table to find the part of the task each has completed. Use the equation work completed = (rate)(time) to fill in the last column cells.

Step-by-step explanation:

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
