What is the slope of the line that passes through the points (-6, -7) and

Effectus [21]

Slope of the line is 0.

Step-by-step explanation:

Given points are,

(-6, -7) and (-24, -7)

Here,

$x_{1} = -6\ \ \ \ \ y_1=-7\\x_2=-24\ \ \ \ \ y_2=-7$

Slope = $\frac{y_2-y_1}{x_2-x_1}$

$Slope = \frac{-7-(-7)}{-24-(-6)}\\Slope=\frac{-7+7}{-24+6}\\Slope=\frac{0}{-18}\\Slope= 0$

Slope of the line is 0.

Keywords: slope, line

a boat takes 4 hours to go 20 miles upstream.It can go 32 miles downstream in same time.Find the rate of the current and the rat

Zinaida [17]

Let

x---------> the rate of the boat in still water in mph

y--------> the rate of the current in mph

we know that

Upstream

$rate=\frac{20}{4} \\\\ rate=5mph$

$x-y=5$ equation $1$

Downstream

$rate=\frac{32}{4} \\\\ rate=8mph$

$x+y=8$ equation $2$

Adds equation $1$ and equation $2$

$x-y=5\\ x+y=8\\ -----\\ 2x=13\\ x=6.5mph$

Find the value of y

$x+y=8\\ y=8-x\\ y=8-6.5\\ y=1.5 mph$

therefore

the answer is

the rate of the boat in still water is $6.5 mph$

the rate of the current is $1.5 mph$

If the sin 90° is 1, then the cos ____ °= _____

lorasvet [3.4K]

That sentence is confusing...

That sentence is confusing...
There is no logical relationship between the prepositions.
You can put any angle and its cosine there.
You can put, for example:

Cos(90)=0 or Cos(0)=1... Both are correct options...

If your teacher wrote that, he doesn't know to write very good...

Good luck!
