The table shows the height of water in a pool as it is being filled. A table showing Height of Water in a Pool with two columns

icang [17]

Answer:

The height of the water increases 2 inches per minute.

Step-by-step explanation:

the slope is always the ratio of

y coordinate change / x coordinate change

in our case, x is the time (minutes), and y is the water height (inches).

we see, the longer the pool get filled, the higher the water gets. logical, right ?

by checking the data points we see :

with every 2 minutes passing the water height increases by 4 inches.

so, the slope is +4/+2 = 2/1 = 2

and that ratio tells us now the increase of the water height with every fraction or multiple of the measured 2-minute interval.

every 2 minutes 4 inches more.

so, e.g. every 3×2 = 6 minutes we get 3×4 = 12 inches more.

and - every 1/2 × 2 = 1 minute more we get 1/2 × 4 = 2 inches more.

Solve x − 2y = 3 for x.

wolverine [178]

Answer:

$x=2y+3$

Step-by-step explanation:

So we have the equation:

$x-2y=3$

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

$(x-2y)+2y=(3)+2y$

On the left, the 2y cancel. Simplify the right:

$x=2y+3$

And we're done!
