The sanchez family and the jenkins family each used their sprinklers last summer. the water output rate for the sanchez family's sprinkler was 15 l per hour. the water output rate for the jenkins family's sprinkler was 35 l per hour. the families used their sprinklers for a combined total of 45 hours, resulting in a total water output of 1075 l. how long was each sprinkler used?
sanchez family:
jenkins family:

step-by-step explanation:

i dont really.know

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

answer: f = 32.2m

step-by-step explanation: that is the answer

after simplifying it i got: -36.25 as my answer. hope that !
