The slope of that line is -1, so m = -1.

The point you were told to use is (-2,2), so point-slope form starts as:

( y - 2 ) = -1 • ( x - (-2) )

But we'd clean up that x-(-2) to be x+2.

y - 2 = -1 ( x+2 )

Solve for x in terms of r, s and t : s=2x+t/r

Anna007 [38]

For this case we have the following equation:

$s = \frac {2x + t} {r}$

We must clear the value of the variable "x" as a function of r, s and t:

If we multiply by "r" on both sides of the equation we have:

$rs =2x + t$

If we subtract "t" on both sides of the equation we have:

$rs-t = 2x$

If we divide by "2" on both sides of the equation we have:

$x = \frac {rs-t} {2}$

Thus, the value of the variable "x" is:

$x = \frac {rs-t} {2}$

Answer:

$x = \frac {rs-t} {2}$

The speed of a stream is 2 mph. A boat travels 20 miles upstream in the same time it takes to travel 40 miles downstream. What i

nataly862011 [7]

Answer:

<em>The speed of a boat in still water is 6 miles per hour. </em>

Step-by-step explanation:

t = $\frac{20}{s-2}$ (upstream)

t = $\frac{40}{s+2}$ (downstream)

$\frac{20}{s-2}$ = $\frac{40}{s+2}$

40 ( s - 2 ) = 20 ( s + 2 )

40s - 80 = 20s + 40

20s = 120

s = 6 mi / h

<em>The speed of a boat in still water is 6 miles per hour.</em>
