Answer: 14x - 11

Step-by-step explanation:

Add 10x and 4x.

14x −15 + 4

Add −15 and 4.

14 x −11

OR.

Apply the distributive property. 5 ( 2 x ) + 5 ⋅ − 3 + 4 ( x + 1 )

Multiply 2 by 5 . 10 x + 5 ⋅ − 3 + 4 ( x + 1 )

Multiply 5 by − 3 . 10 x − 15 + 4 ( x + 1 )

Apply the distributive property. 10 x − 15 + 4 x + 4 ⋅ 1

Multiply 4 by 1 . 10 x − 15 + 4 x + 4

hoped this helped lmk if it did

What is the value of x?

soldi70 [24.7K]

Answer:

$5\sqrt{3}$

Step-by-step explanation:

A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:

The side opposite the 30* angle = a

The side opposite the 60* angle = $a\sqrt{3}$

The side opposite the 90* angle = 2a

(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")

They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:

Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.

Once we know what "a" is, we can fill in the rest:

30* = 5

60* = $5\sqrt{3}$

90* = 10

The independent variable in the relationship is the Number of Months and should be placed on the x-axis

The dependent variable in the relationship is the Number of Fish and should be placed on the y-axis

Step-by-step explanation:

Let us explain the independent and dependent variables of a relation

The independent variable is the input of the relation

The dependent variable is the output of the relation
The values of dependent variables depend on the values of independent variables
When the relation represented graphically the independent variable placed on the x-axis and the dependent variable placed on the y-axis

The table:

→ Number of Months: 0 : 1 : 2 : 3 : 4

→ Number of Fish : 1,024 : 1,280 : 1600 : 2,000 : 2,500

Let us check is their any constant ratio between the consecutive values of the number of fish

∵ 1,280 ÷ 1,024 = 1.25

∵ 1,600 ÷ 1.280 = 1.25

∵ 2,000 ÷ 1,600 = 1.25

∵ 2,500 ÷ 2,000 = 1.25

∴ The table represent an exponential function, where the input

is the number of months and the output is the number of fish

∵ The input is independent variable

∴ The independent variable is the number of months

∵ The output is the dependent variable

∴ The dependent variable is the number of fish

∵ The independent variable is placed on the x-axis

∴ The number of months should be place on the x-axis

∵ The dependent variable is placed on the y-axis

∴ The number of fish should be place on the y-axis

The independent variable in the relationship is the Number of Months and should be placed on the x-axis

The dependent variable in the relationship is the Number of Fish and should be placed on the y-axis

An analyst for a new company used the first three years of revenue data to project future revenue for the company. The analyst p

Westkost [7]

Using limits, it is found that since $\lim_{x \rightarrow \infty} f(x) < 0$ , the company is expected to operate at a loss, hence it is not expected to be successful.

The revenue function is given by:

$f(x) = -2x^5 + 6x^4 - x^3 + 5x^2 + 6x + 50$

<h3>Limit:</h3>

The projected revenue over the long-term is given by the limit of f(x) as x goes to infinity.

Then:

$\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} -2x^5 + 6x^4 - x^3 + 5x^2 + 6x + 50 = \lim_{x \rightarrow \infty} -2x^5 = -2(\infty)^5 = -\infty$

Since the limit is negative, the company is expected to operate at a loss, hence not being successful.

Law Incorporation [45]

Answer:No. A strong correlation does not imply causation.

Step-by-step explanation:

Cause and effect relationship is not explained by correlations. A cause and effect relationship can only be established by carrying out carefully controlled experiments.

Hence, a strong correlation between the the intake of soda and accidents does not necessarily imply that soda intake causes accident.

A lurking variable in this study may be the speed of the drivers. A lurking variable is not controlled but significantly impacts results obtained from the study.

Since the speed of the drivers is not strictly controlled, it may just be a lurking variable.
