(x+1)(x-2) / (x-2)(x+3) = (x+1)/(x+3)

The simplification of the given rational expression when x is not equal to 2 or negative 3 is determined as (x + 1)/(x + 3).

The simplification of the given expression when x is not equal to 2 or negative 3 is determined as follows;

[tex]= \frac{(x + 1)(x -2)}{(x-2)(x + 3)}[/tex]

cancel "x-2" since it is common to numerator and denominator

[tex]= \frac{(x + 1)}{(x + 3)}[/tex]

Thus, the simplification of the given rational expression when x is not equal to 2 or negative 3 is determined as (x + 1)/(x + 3).

Step-by-step explanation:

Answer: x=8

Step-by-step explanation:

4x+6y=50

4x+6(3)=50

4x+18=50

4x=32

x=8

The value of x when y = 3 in the linear function 4x + 6y = 50 is x = 8.

Use the concept of linear fucntion defined as:

The formula for a linear function is f(x) = mx + b, where m and b are real values. The slope-intercept form of a line is represented by the equation,

y = mx + b.

The given linear fucntion is:

4x+6y= 50

To find the value of x when y = 3,

Substitute y with 3 in the equation and solve for x.

4x + 6(3) = 50

4x + 18 = 50

To isolate x,

Subtract 18 from both sides:

4x = 50 - 18

4x = 32

Now we divide both sides by 4:

x = 32/4

x = 8

Hence,

When y = 3, the value of x in the linear function 4x + 6y = 50 is 8.

If the mean span of automobile tires is 34000 miles and standard deviation is 2350 miles then the z scores that corresponds to the life spans of sample showing 33000 miles,37000 miles and 32000 miles are -0.4255, 1.2766 and -2.1277.

Given that mean span of automobile tire is 34000 miles and standard deviation is 2350 miles.

We are required to find the z score of the sample of 33,000 miles, 37,000 miles, and 32,000 miles.

A z-score basically gives us an idea of how far from the mean a data point is.

Z=(X-μ)/σ

In our case we have to find the mean of life span of three samples.

For the life span of 33000 miles,

Z=(33000-34000)/2350

=-1000/2350

=-0.4255

For the life span of 37000 miles,

Z=(37000-34000)/2350

=3000/2350

=1.2766

For the life span of 32000 miles,

Z=(32000-37000)/2350

=-5000/2350

=-2.1277

Hence if the mean span of automobile tires is 34000 miles and standard deviation is 2350 miles then the z scores that corresponds to the life spans of sample showing 33000 miles,37000 miles and 32000 miles are -0.4255, 1.2766 and -2.1277.

If the sum of a number and three is ​tripled the result is one less than twice the number. The number is 14.

Write an equation and expressions by defining variables first.

"a number" is x.

Then "the sum of a number and three is tripled" is 3(x+3).

And "five less than twice the number" is 2x - 5.

Set them equal and solve for x.

3(x+3) = 2x -5

3x+9 = 2x-5

x+9 = -5

x = -14

Let take "number" is x.

Then from given "the sum of a number x and 3 is tripled" is 3(x+3).

And "twice the number x  and less then 1" is 2x - 1.

Set them equal and solve for x.

3(x+3) = 2x -1

3x+9 = 2x-1

x+9 = -1

x = -1-9

The value of given function is  f'(x)=4 e^sin(x)cos (x)

The derivative is what calculus is all about. The instantaneous pace at which a function changes with regard to one of its variables is known as the derivative. Finding the slope of the tangent line to the function at a given point is equal to doing this.

f'(x) =  d/dx ( 4 e^sin(x))

using differential rule d/dx (a x f ) = a x d/dx(f)

f'(x) = 4 x d/dx ( e ^ sin(x))

use the chain rule

f'(x)= 4 x d/dg ( e^g) x d/dx (sin (x))

f'(x)= 4 e^g x d/dx (sin (x))

f'(x)= 4 e^g x cos (x)

f'(x)=4 e^sin(x) x cos (x)

The equation can be defined as a mathematical term that refers to a situation in which several factors must be considered. It is defined as the state of being equal and is frequently represented as a math expression with equal numbers on either side.

Two expressions joined by an equal sign form a mathematical statement known as an equation.

Shalu's brother was born 2 years before Shalu.  

Shalu's sister was born 4 years after Shalu.  

And the sum of Shalu's brother and sister's age is 30 years. 

Let x be the age of Shalu.  

As Shalu's brother was born 2 years before her = x + 2

As Shalu's sister was born 4 years after her = x - 4.

Therefore,  

x + 2 + x - 4 = 30

2x - 2 = 30

Adding 2 on each side of the equation,

2x -2 + 2 = 30 + 2

2x = 32

Dividing each side of the equation by 2.

2x / 2 = 32 / 2

x = 16

Therefore, Shalu is 16 years old.
