Domain = [0 , +∞)

5x-8y=40 what is the x intercept
Artist 52 [7]
Hello! The x-intercept is where the line crosses the x-axis when y = 0. We already have the expression shown. We will plug in 0 as y to get this:

5x - 8(0) = 40.

As you probably know, anything times 0 is 0, so -8 * 0 is 0. All we have is 5x = 40. Divide each side by 5 to isolate the x. 5x/5 cancels out. 40/5 is 8. There. x = 8. The x-intercept is (8, 0).

The data below represents the number of hours an office assistant spends on the phone every week for 15 weeks.
Veronika [31]

A box plot contains two dots placed at the ends of the data for the mininum and the maximum value with a line placed over the median.

Let's put the numbers in your set in order from low to high:

5

6

7

8

9

9

9

10

12

14

17

17

18

19

19

The median is the middle number. We have 15 numbers so we select the 8th number - 7 from each end. In this set, 10 is the median.

Only one box plot has dots at 5 and 19 and a median of 10 - choice B. Thus, B is the proper box plot.
