a hotel has 18 floors. the hotel owner believes the number 13 is unlucky. the first 12 floors are numbered from 1 to 12. floor 13 is numbered 14, and the remaining floors are numbered from 15 to 19. the hotel manager starts on the top floor of the apartment building. he rides the elevator two floors down. the doors open and a hotel guest gets in. they ride the elevator three floors down. the hotel guest gets off the elevator. the hotel manager rides the elevator the remaining floors down to the first floor. a. write an addition expression using negative integers to show the number of floors the hotel manager rode down in the elevator. b. on what floor did the hotel guest get off the elevator? explain.

The answer for A would be 18 + -17. I'm not sure about B, you may need another user's help.

Hope this helps in any way possible!

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
