4s = 3r
<span>s = 3/4*r </span>
<span>plug this into the second eqution and solve for the other variable: </span>
<span>2r +5(3/4)r = 23 </span>
<span>23/4*r = 23 </span>
<span>r = 4 </span>
<span>plug this r into the above equation we solved: </span>
<span>s = 3/4*r </span>
<span>s = 3/4*4 </span>
<span>s = 3 </span>
<span>system is: </span>
<span>{r=4, s=3}</span>
<u>Answer-</u>
<em>Equation 1</em><em> is the equation which represents the graph.</em>
<u>Solution-</u>
From the graph it can be noticed that, the function is a hyperbola. It is a rectangular hyperbola.
The general form of rectangular hyperbola is,

Where c is a constant.
Equation 1 represents a function of rectangular hyperbola, with vertical asymptote as x=-2 .
Equation 2 represents an exponential function.
Equation 2 represents an cubic function.
Equation 2 represents logarithmic function.
Therefore, equation 1 is the equation which represents the graph.
Let the speed of the current be x and the speed of the canoe in still water be y, then

Adding the two equations, we have:

From any of the equations, we have that x = 2
Therefore, the speed of the current is 2 miles per hour while the speed of the canoe in still water is 5 miles per hour.
Answer:
(x-3)^2+(y+2)^2=144
Step-by-step explanation:
Answer:
The answer is C.
Step-by-step explanation:
When we see something with a high correlation coefficient, we know that these two things trend in the same direction (which eliminates D). However, we must remember that correlation does not mean causation, so A and B are also out.
