Answer:

$- \frac{4}{5}$

Step-by-step explanation:

Line is passing through the points R (0, 4), S (5, 0)

$Slope \: of \: RS \\ = \frac{4 - 0}{0 - 5} \\ \\ = \frac{4}{ - 5} \\ \\ = - \frac{4}{5}$

Answer: b=2(square root of 2) and a=4

Step-by-step explanation:

Since this is a 45-45-90 triangle we know that side b is equal to $b=2\sqrt{2}$ .

In a 45-45-90 triangle, the hypotenuse is equal to $x\sqrt{2}$ this means in order to find missing side length a, we have to multiply $(2\sqrt{2})(\sqrt{2})$ this will give us 4

so the missing side lengths are, $b=2\sqrt{2}$ and $a=4$

Answer:

The value of x is -2 and 2.

Step-by-step explanation:

When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :

x² - 3x - 1 = -3x + 3

x² - 3x - 1 + 3x - 3 = 0

x² - 4 = 0

Next, you have to factorize and solve it :

x² - 4 = 0

x² + 2x - 2x - 4 = 0

x(x + 2) - 2(x + 2) = 0

(x + 2)(x - 2) = 0

x + 2 = 0

x = -2

x - 2 = 0

x = 2

Can someone pls help me pls

Answer:

Step-by-step explanation:

Usually, we represent losses with negative numbers. Using that representation, a loss of $975 would be represented by the integer -975.

The additive inverse of this number is also called its "opposite." It is found by changing the sign: additive inverse = +975.

The sum of a number and its additive inverse is zero. The opposite of a loss is a gain. The value +975 represents the gain (the investment's earnings) that would bring the net change in investment value back to zero.

A disc jockey has 20 songs to choose from and can only play 8 in the next half hour. how many different playlists are possible?

motikmotik

This problem is a combination problem since it did not indicate that there is a specified order of songs to be played. The type of combination problem is without repetition. Thus the working equation would be n!/r!(n-r)! wherein n is the total number of songs to choose from and r is the number of songs you can choose at a given time. The answer would be 125970.
