Mai earns $7 per hour mowing her neighbors lawns. she also earns $14 for hauling away bags of recyclables for some neigbors. priya babysits her neigbors children. the table shows the amount of monet m she earnd in h hours. priya and mai have agreed to go to the movies the weekend after they have earned the same amount of money for the same number of work hours. how many hours do theyhave to work before they go to the movies?

By creating a system of linear equations, the number of hours worked before they go to the movies is 10 hours.

Priya's earning :

Total earning, m = 8.40h - - - - (1)

Mai's Earning :

Total earning = 14 + 7h - - - - (2)

Equating (1) and (2) ;

8.40h = 14 + 7h

8.40h - 7h = 14

1.40h = 14

h = 14 ÷ 1.4

h = 10 hours

Therefore, they'll have to work for 10 hours

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
