The newspaper in haventown had a circulation of 80,000 papers in the year 2000. in 2010, the circulation was 50,000. with x = 0 representing the year 2000, the graph below models this scenario. what number will complete the point-slope equation that models this scenario? y 50,000 = (x 10)

-3000

Explanation:

The missing number is the slope of the line.

To calculate the slope, we use the formula

Using the points (0, 80000) and (10, 50000) [remember, the year 2000 is at x = 0; this means the year 2010 would be at x=10] we have:

m = (50000-80000)/(10-0) = -30000/10 = -3000

The missing number, the slope, is -3000.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
