Solve -2(2x+5) -3(x-1)
OLEGan [10]
<h2>Hello!</h2>

The answer is:

-2(2x+5)-3(x-1)=-7x-7\\

<h2>Why?</h2>

To solve the problem, we need to perform the operations and then, add like terms.

We need to apply the distributive property, which is defined by the following way:

a(b+c)=ab+ac

Also, we need to remember how to add like terms. Like terms are terms that share the same exponent and the same variable, for example:

3x+5x+x^{2}=8x+x^{2}

We were able to add only the first two terms since they are like terms, both are sharing the same exponent and the same variable.

So, we are given the expression:

-2(2x+5)-3(x-1)

Then, solving we have:

-2(2x+5)-3(x-1)=-4x-10-(3x-3)\\\\-4x-10-(3x-3)=-4x-10-3x+3\\\\-4x-10-3x+3=-4x-3x-10+3\\\\-4x-3x-10+3=-7x-7

Hence, we have that the answer is:

-2(2x+5)-3(x-1)=-7x-7\\

Have a nice day!

What is the slope of the line that passes through the points (-9, -2) and (-9,-6 )? Write in simplest form
Korvikt [17]

Hello.

There are really 2 ways to think about the given problem.

First, we can use the slope formula:

\displaystyle\frac{y2-y1}{x2-x1}

\displaystyle\frac{-6-(-2)}{-9-(-9)} =\frac{-6+2}{-9+9} =\frac{-4}{0} =

Slope = undefined

The second way is to just take a look at the points.

You should notice that the x-coordinates are the same.'

If the x-coordinates are the same, then the slope is

\Large\boxed{Und.efined}}

I hope it helps.

Have a nice day.

You want to invest in companies belonging to Gispa Group of
marysya [2.9K]

Answer:

0.1007

Step-by-step explanation:

Given :

Average gain, μ = 0.8

Standard deviation, σ = 0.7

Number of companies, n = 20

Obtaining the standardized value ;

Zscore = (x - mean) / (σ/√n)

Zscore = (1 - 0.8) / (0.7/√20)

Zscore = (0.2 / 0.1565247)

Z = 1.27775

Using the Z probability calculator :

P(Z > 1.27775) = 0.10067

P(Z > 1.27775) = 0.1007 ( Z probability calculator)
