Radical 2x+5 equals x

1. Square both side.

2x+5 equals x square

Move everything to one side.
X square-2x-5=0

Since this time, we can't factor very well. We need to use the quadratic formula.

-b+- square root b square- 4ac divided by 2a

This gives: -(-2)* square root( 4-4(1)(5))/ 2

Notice that we get 2 plus and minus square root of -16.

Which is an imagery/ complex solution.

The value of x could be 2+i4/2 or 2-i4/2

What are transformation possible to change f(x) to g(x) on graph linear equation
Korolek [52]

Answer:

<h2>Vertical stretch or compression and vertical shift.</h2>

Step-by-step explanation:

When we talk about the transformation of functions, we can mention stretching, rotating, dilating, shifting. However, when we want to transform linear functions, there are only two transformations that are worthy in that case, those are vertical stretch or compression and vertical shift.

Now, you may ask, why only vertical transformation? the reason behind that is because horizontal transformation would give the exact same result because it's only a straight line which we are transforming.

Another common question would be, why only two transformations? it's because with these two you can get all the results because it's a straight line.

The image attached shows examples of this.

Jack needs 22 pirates for every 2 pirate ships he manages
AysviL [449]

Answer:

55 pirates for 5 ships, 121 pirates for 11 ships

Step-by-step explanation:

for every 2 ships he needs 22 pirates, divide both by 2 and we see that for every ship he needs 11 pirates, also can write as 2x= 22 and divide both sides by 2, x=11 now that we know for every ship he needs 11 pirates we just multiply 11 times the amount of ships or 11x=y, 11 times 5 is 55 and 11 times 11 is 121

The distribution of the amount of money in savings accounts for University of Alabama students has an average of 950 dollars and
Pavlova-9 [17]

Answer:

Approximately Normal, with a mean of 950 and a standard error of 158.11

Step-by-step explanation:

To solve this question, we need to understand the Central Limit Theorem.

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation, which is also called standard error s = \frac{\sigma}{\sqrt{n}}.

In this problem, we have that:

\mu = 950, \sigma = 1000

The sampling distribution of the sample mean amount of money in a savings account is

By the Central Limit Theorem, approximately normal with mean \mu = 950 and standard error s = \frac{1000}{\sqrt{40}} = 158.11

So the correct answer is:

Approximately Normal, with a mean of 950 and a standard error of 158.11
