HELP!!! 25 POINTE AND BRAINLIEST!! a local cafe sells 7,200 cold beverages in the month of july. over the next six months, the number of cold beverages decreases at an average rate of 750 cups per month. During the same time frame, the number of hot beverages sold is represented by the equation y=900x + 3,300 where the number of hot beverages, y, is a function of x, the number of months after july.

A. what is the rate of change of cold beverages sold per month? hot beverages?

B. which rate of change is greater? what does it mean?

Answers

Answer: a. The rate of change of cold beverages: -750 cups/month

The rate of change of hot beverages: 900 cups/month

b. The rate of change of hot beverages is greater (900 > -750). It means that the number of hot beverages sold increases at a rate of 900 cups every month.

Step-by-step explanation:

a. The question says that "the number of cold beverages decreases at an average rate of 750 cups per month". This indicates that the rate of change of cold beverages is -750 cups/month. Why negative? Remember that it decreases, not increases.

Then let's look at the equation given for the sale of hot beverages:

y=900x + 3,300

The slope of the equation is 900, which is also the rate of change. So the rate of change of hot beverages is 900

what is the slope of the line graphed below? (3,3) (0,-6)

Answers

Answer:

Where is the line

Step-by-step explanation:

Answer:

The slope of the lines is 3.

Step-by-step explanation:

Since I can't actually graph it, we can make a table

x      y

3      3

0     -6

From 3 to -6, you subtract 9 (for the y section)

From 3 to 0, you subtract 3 (for the x section)

Now all you need to do is divide y by x

y/x = -9/-3 = 3

It's a positive 3, because two negatives times each other will always result in a positive.

Slope = 3

The perimeter of a rectangular meadow is 1004 m. What
will be the sum of the length and breadth of the meadow ?​

Answers

Answer:

hope it works for u

Step-by-step explanation:

Given the length of the rectangle = l

the breadth  of the rectangle = b

perimeter of the rectangle = sum of length of all sides of the rectangle  

                                             = l+ b+ l+ b

                                             =2 l+2 b

                                             =2( l+ b)

∴ perimeter of the rectangle =2( l+ b)

as given perimeter = 1004 m

hence ,

2(l+ b)= 1004

(l+ b)=1004/2  = 502 m

l+ b=502 m
