You use a garden hose to fill a wading pool. If the water level rises 15 centimeters every 7 minutes and you record the data point of (21,y), what is the value of y? Use slope to justify your answer The rate of change at which the water level rises is centimeters per minute. So, solving equation for y gives a y-value to .

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
