Answer:

<em>16.5 gallons per minute.</em>

Step-by-step explanation:

The given table is:

$\begin{center}\begin{tabular}{ c c } Time(minutes) & Water(gallons) \\ 1 & 16.50 \\ 1.5 & 24.75 \\ 2 & 33 \\\end{tabular}\end{center}$

We are given this linear function in the form of table.

Let 't' be the time and W(t) be the function with which the gallons of water are changing with time.

We can use slope intercept form to find the equation.

$y=mx+c$

Slope of a function:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$x_2 = 1.5\\x_1 = 1\\y_2 = 24.75\\y_1 = 16.50$

$m=\dfrac{24.75-16.50}{1.5-1}\\\Rightarrow m =16.5$

This slope is the constant of proportionality.

i.e. the rate at which the number of gallons are changing per minute.

So, the answer is <em>16.5 gallons per minute.</em>

How to solve inequaities?

Elza [17]

$-3(-8+5m) > 5(6-3m)\qquad|\text{use distributive property}\\\\(-3)(-8)+(-3)(5m) > (5)(6)+(5)(-3m)\\\\24-15m > 30-15m\qquad|\text{add 15m to both sides}\\\\24 > 30\qquad FALSE\\\\\text{Therefore your answer:}\ \boxed{NO\ SOLUTION}\to m\in\O$

Answer:

Step-by-step explanation:

Next time please share the answer choices. Thanks.

Because the common factor 0.75 is less than 1 (but greater than 0), we know that this is a decaying function. As x increases, the graph approaches the x-axis (that is, the line y = 0).
