Carson is draining his swimming pool so he can clean it. The water level started at 12 feet and decreased 6 inches every hour. Which equation provides the water level of the swimming poolo(in feet) as a function of time (in hours)? y=1/2x-12, y=-6x+12, y=-1/2x+12, y=6x-12

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.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

what is

step-by-step explanation:

yes.. it's proven to be 36.
