The illustration below shows the graph of y as a function of x. Complete the following sentences based on the graph.

Initially, as x increases, y (decreases, increases, or is constant)

Afterward, the slope of the graph of the function is equal to for all x between x=3 and x=5.

The slope of the graph is equal to for x between x=5 and x=9.

The greatest value of y is y=and it occurs when x=

.

1). Increases

2). Slope = 4

3). Slope = -1

4). y = 4 when x = 5

Step-by-step explanation:

1). Initially, as x increases, y also increases. (Linear growth has been shown in the graph initially).

2). Afterward, the slope of the graph of the function is equal to 4 for all x between x = 3 and x = 5.

hi there!

the answer will be d: 2

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
