Are the equations 9x=5x+4 and 14x=4 equivilant?​

Answer:

No

Step-by-step explanation:

First solve both equations:

1) 9x = 5x + 4

Simplifying

9x = 5x + 4

Reorder the terms:

9x = 4 + 5x

Solving

9x = 4 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

9x + -5x = 4 + 5x + -5x

Combine like terms: 9x + -5x = 4x

4x = 4 + 5x + -5x

Combine like terms: 5x + -5x = 0

4x = 4 + 0

4x = 4

Divide each side by '4'.

x = 1

Simplifying

x = 1

2) 14x = 4

14x = 4 (divide both sides by 14 to get x)

14x/14 = 4/14

x = 0.285714285714

As you can see, the value of x in the second equations is less than one, therefore making these algebraic equations not equivalent.

Answer:

No

Step-by-step explanation:

9x=5x+4 and 14x=4

9x= 5x+4

Subtract 5x from each side

9x-5x = 5x+4-5x

4x= 4

The equations are not the same

Lettuce is planted on a 46​-acre field. The field is divided into​ one-acre subplots. A sample is taken from each subplot to est
nalin [4]

The correct answer is B. Stratified sampling is​ used since the field is divided into subplots and a random sample is taken from each subplot.

Explanation:

Sampling refers to the process followed by researchers to select a group of individuals from a larger group; considering in most studies it is not possible to analyze all the population. In the case of stratified sampling, this involves dividing the general population into smaller groups, which are known as strata; after this, the researcher selects a specific number of individuals from each strata. This method guarantees the sample is selected randomly, and therefore the study is not biased. Stratified sampling was the method used in the example described because, in this, the general population (46-acre field) was divided into subplots that represent the strata. Also, after this, the researcher selected one random sample.

Indicate a general rule for the nth term of the sequence a1 = 2 and r = √3.
pantera1 [17]

It is given in the question that,

a_{1} = 2, r = \sqrt 3

Since we have the value of r given, so we have to use the formula to find the nth term of the geometric progression, which is

a_{n} = a(r)^{n-1}

Substituting the values of a and r, we will get

a_{n} = 2( \sqrt 3)^{n-1}

So the correct option is the third option .
