Answer: -20

Step 1: Write an equation

To start off, we will need to write an equation. To do so, we will use the equation for slope, using rise/run. M represents the slope.

M= rise/ run

Step 2: Substitute information

Now that we know the equation, we can substitute information given to us in the question. Let’s start by replacing m with -5, as we are told that this is the slope.

M= rise/ run
-5= rise/ run

Great! Now let’s change the run. The run is said to be 4, so we will put this on the bottom of the fraction, under the rise.

-5= rise/ run
-5= rise/4

Step 3: Solve

Now that we have our final equation, we can solve for the rise. We can do so by getting rise alone on the right side, by undoing the division. Let’s multiply each term by 4, isolating rise in the process.

-5= rise/4
-5 (4)= rise/4 (4)
-20= rise

Step 4: Check your answer

For our rise, we got -20 as an answer. Let’s check if this is correct by getting the original equation, and substituting all of our information.

M= rise/ run
-5= -20/4
-5= -5

This is correct! The rise is -5. Hope this helps! Comment below for more questions.

Answer:

x = -1

Step-by-step explanation:

$\frac{2}{3} - 4x + \frac{7}{2} = -9x + \frac{5}{6}$

Add 4x to each side of the equation

$\frac{2}{3} - 4x + \frac{7}{2} + 4x = -9x + \frac{5}{6} + 4x$

$\frac{2}{3} + \frac{7}{2} = -9x + \frac{5}{6} + 4x$

Subtract ⅚ from each side

$\frac{2}{3} + \frac{7}{2} - \frac{5}{6} = -9x + \frac{5}{6} + 4x - \frac{5}{6}$

$\frac{2}{3} + \frac{7}{2} - \frac{5}{6} = -9x + 4x$

$\frac{4 + 21 + 5}{6} = -5x$

$\frac{30}{6} = -5x$

$5 = -5x$

Divide both sides by -5

$\frac{5}{-5} = \frac{-5x}{-5}$

$-1 = x$

$x = -1$

The selected statistical questions are as follows:

A what is the typical amount of rainfall for the month of June in the Galapagos islands

D how many songs does the class usually listen to each day

G how long does it typically take for 2nd graders to walk a lap around the track

Statistical questions are known by these two main characteristics:

they are answered by the collection of data
there is always variability in the data collected

This means that the data vary. They are not the same data. For example, "How old is Monday?" is not a statistical question because it has one answer.

Thus, statistical questions are not answered by a single number or answer, especially when the correct answer is just one.

We have the Trigonometric Identities : secx = 1/cosx; (sinx)^2 + (cosx)^2 = 1;
Then, 1 / (1-secx) = 1 / ( 1 - 1/cosx) = 1 / [(cosx - 1)/cosx] = cosx /
(cosx - 1 ) ;
Similar, 1 / (1+secx) = cosx / (1 + cosx) ;
cosx / (cosx - 1) + cosx / (1 + cosx) = [cosx(1 + cosx) + cosx (cosx - 1)] / [ (cosx - 1)(cox + 1)] =[cosx( 1 + cosx + cosx - 1 )] / [ (cosx - 1)(cox + 1)] = 2(cosx)^2 / [(cosx)^2 - (sinx)^2] = 2(cosx)^2 / (-1) = - 2(cosx)^2;
