HELP ASAP plz I’ll give brainliest and plz explain:)
yaroslaw [1]

Answer: No, Store A is charging $2.20 per rose while Store B is charging 2.166667 dollars per rose.

Step-by-step explanation:

11/5 = 2.2

(To check) 2.2 x 5 also equals $11

However, they are not selling roses at the same rate because if you were to do 2.2x6 it will equal 13.2.

13/6 = 2.166667

Find the average rate of change of the number of digital cameras sold from 2006 to 2015
asambeis [7]

Answer:

5900 units per year  

Step-by-step explanation:

The average rate of change  from (x₁, y₁) to (x₂, y₂) is the slope of the straight line joining the two points.

slope = (y₂ - y₁)/(x₂ - x₁)

From the graph, I estimate your points to be (2006, 35 000) and (2015, 88 000).  

slope = (88 000 - 35 000)/(2015 - 2006) = 53 000/9 ≈ 5900 units per year

The  average rate of change in the number of digital cameras sold between 2006 and 2015 was 5900 units per year.

by drawing two straight lines divide the face of the clock into three regions such that the numbers in each regions have the sam
Alika [10]
78 (1 + 2 + 3 . . + 12) so 78/3 = 26  and 11 + 12 + 1 + 2

10 + 9 + 3 + 4

8 + 7 + 6 + 5

that means you will draw one line below the 11 and across to below the 2 and the second line would be above the 8 and across to below the 4. 

Seeing is believing . . .draw and label a clock face then add the two lines!
