The table shows the linear relationship in a tank and time. what is the rate of the change of water level feet per hour? also explain how

y = slope (x) + y - intercept

To find the slope we need to find out how much the x's and y's increase or decrease...

To find the y - intercept if any, simply look for coordinates ( 0 , y ) or 0 and a #.

~~

In this case, as time passes, the water level decreases therefore we have a negative slope.

Time is our x and amount (ft) is our y.

On the x side it increases by 2

On the y side it decreases by 10

Now do y over x ==> 10 over 2 and get 5 ==> m

-5 is our slope and 50 is our y - intercept

~~

The "rate of change" is another word for slope.

Well, slope is - 5ft is our slope.

I hope that helps you out!!

Any more questions, please feel free to ask me and I will gladly help you out!!

1/2 * (5+3) * 6 = 24 cm^2

Step-by-step explanation:

Perimeter is 20

and it's a rectangle so 2x + 12= 20

x is 4 so one of parallel side of trapezium is 9-4 or 5 then just apply formula for area of trapezium
