Look at the values on the axes of the graph.

Step-by-step explanation:

Domain can be found by looking at the x-axis of a graph. Range can be found by looking at the y-axis of a graph. You have to find at what point on the axis is the graph stopping.

For example, if I wanted the domain of y=x, I would say it is all real numbers. Why? Because when we look along the x-axis, from left to right, we can see that it continues going until infinity. That means that there are no stopping points in the graph of y=x.

I fill an aquarium to a depth of 3/8 meters in 6 minutes. What is the unit rate in minutes per meter?

Elena L [17]

Answer:

16 minutes per meter

Step-by-step explanation:

Depth = 3/8 meters

Time taken = 6 minutes

What is the unit rate in minutes per meter?

Time taken per depth = minutes per meter

Unit rate in minutes per meter = 6 minutes ÷ 3/8 meters

= 6 minutes × 8/3 meters

= 48/3

= 16 minutes per meter

How do you graph a circle x^2 + y^2=25 and the line is given y=2

Kazeer [188]

$\bf \textit{equation of a circle}\\\\ 
(x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2
\qquad 
\begin{array}{lllll}
center\ (&{{ h}},&{{ k}})\qquad 
radius=&{{ r}}
\end{array}\\\\
-------------------------------\\\\
x^2+y^2=25\implies (x-0)^2+(y-0)^2=5^2$

so notice above, the circle is centered at h,k or 0,0, the origin, and has a ratio of 5.

and y = 2, is just a horizontal line, check the picture below.
