Can someone explain how I would get the answer to this?

The graph of a function f is the set of all points in the plane of the form (x, f(x)).

Step 1

iven

g(x) is a transformation of the function f(x)we have a root in the function, note that the variable x is inside the root, so we can conclude the basic function is

square tooroot

Step 2

rove

ow, lets's check the transformation of f(x)

a)1 was subtracted form the argument of the fucnction

when you subtract a number b form the argument of the function you are shifting the function b units to the rigth

so

he function was shifteed 1 unit to rigth

) the resulting function was multiplied by 2-

when you multplie by a negavitve constant you are reflecting the funciton acrros x-axis, and is is stretched vertically.

so

he funcition was reflected across x-axis an strtched vertically by a factor of 2

c) 4 was added to the function

when you add a constant b to any function, the graph will be shifted b units up,so

he functinon was shifted 4 units up

hrerefore, we can conclude the answer is

I hope this helps you

The x and y solution of the system  is x = -3 and y = -6

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

6 = −4x + y

− 5x − y = 21

Make -y the subject in the second equation, by adding 5x to both sides of the equation

5x − 5x − y = 21 + 5x

This gives

−y = 21 + 5x

Substitute −y = 21 + 5x in 6 = −4x + y

6 = −4x - 21 - 5x

Evaluate the like terms

5x + 4x = -6 - 21

This gives

9x = -27

So, we have

x = -3

Substitute x = -3 in −y = 21 + 5x

−y = 21 + 5 * -3

Evaluate

−y = 6

So, we have

y = -6

Hence, the solution for the system of linear equations 6 = −4x + y and − 5x − y = 21 is x = -3 and y = -6

The length and width of the rectangle with a perimeter of 378ft are 168ft and 21ft respectively.

The formula used in calculating the perimeter of a rectangle is expressed as;

P = 2( l + w )

Where l is length and w is width.

Given the data in the question;

Let 'x' represent the width of the rectangle.

Plug the given values into perimeter formula and solve for x .

P = 2( l + w )

378 = 2( 8x + x )

378 = 2( 9x )

378 = 18x

18x = 378

x = 378/18

x = 21

Now, we find the length and width of the rectangle.

Width of the rectangle w = x = 21ft

Length of the rectangle l = 8x = 8( 21 ) = 168ft

Therefore, the width of the rectangle is 21ft while its length is 168ft.

If a = b then a - c = b - c; Subtraction Property of =

Properties of equality includes; addition, subtraction, transitive, reflexive, and symmetric properties of equality

The transitive property of equality can be stated as follows; If two variables are each equal to a third variable, then the two variables are equal to each other.

Therefore; a = b and b = c then a = c represents the transitive property

The division property states that both sides of an equation remain equal, following a division of both sides by the same non zero number

Therefore;

If a = b then a ÷ c = b ÷ c; represents the division property of equality

The reflexive property of equality states that a measure or number is always equal to itself

Therefore;

a = a represents the reflexive property

Substitution property indicates that if two variables are equal, then one can replace the other in an equation and the results will remain the same

Therefore;

If x + a = b and x = c then c + a = b; represents the substitution property

The statement of the addition (and subtraction) property of equality is that both sides of an equation remain equal following the addition or subtraction of the same amount from both sides the same

Therefore;

If a = b then a + c = b + c; represents the addition property of equality

If a = b then a - c = b - c; represents the subtraction property of equality

This states that both sides of an equation remain equal following the multiplication of both sides by the same value

The symmetric property states that two sides of an equation remain equal when their relative positions are interchanged

This states that two sides of an equation remain equal following a distribution with multiplication over addition or subtraction.

The expected value denotes potential. The occurrence of a random event is the subject. Its fundamental notion is that something is probable to occur.

Actually, the anticipated value may be viewed as the mean of a random variable.

Answer:

y = mx

Step-by-step explanation:

It depends on what form of the line that you want.  Usually the slope intercept form is wanted.

y = mx + b  We need to have the m (slope) and the b (the y-intercept)

The slope is the change in y over the change in x.

Ordered pairs are in the form (x,y)

(0,0) and (4,4)  Have x's of 4 and 0, and y's of 4 and 0.  We subtract these to find the changes in y and x.

[tex]\frac{4-0}{4-0}[/tex]  This is [tex]\frac{4}{4}[/tex] which is the same as 1. The slope (m) is 1.

Now we need to find the y -intercept.  The y intercept is the point where x is 0  (0,b).  They give us this point (0,0,)  So the y -intercept is zero.

y = 1m + 0

or y =mx

Considering the definition of greatest common divisor, the greatest number of backpacks volunteers can prepare using all of the maps and dictionaries is 8.

Considering that a divisor can be formally defined as that number that is contained in another exactly n times, the greatest common divisor is the largest number by which two or more numbers can be divided. That is, the greatest common factor is the highest number by which a set of numbers can be divided, resulting in a whole number.

To calculate the greatest common factor, the following steps must be followed:

In this case, you must calculate the greatest common factor as follows:

Answer:

First, let one angle be a variable (eg: x) so that you can form expressions and solve.

Let the first angle be x°.

Then we can form expressions for the second and third angles using the information given.

First angle = x°

Second angle = (x + 10)°

Third angle = (3x)°

Since sum of angles in a triangle is 180°, we can form an equation.

x + (x + 10) + 3x = 180

Simplify and solve for x.

5x + 10 = 180

5x = 170

x = 34

Substitute x into the expressions to find the angles.

First angle = 34°

Second angle = 34 + 10

= 44°

Third angle = 3(34)

= 102°

The worth of the share after a 15% fall will be $47.21.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the value of a share of stock on the stock market decreased by 15%. If it used to be worth $55.55.

The value of the share after 15% fall will be calculated as:-

Decreased amount = 55.55 - ( 55.55 x ( 15 / 100)

Present age of father is 48 years and that of son is 23 years.

Let the age of father be x years

And the son's age be y years

According to the question,

x - y = 25 -----------1

15 Years ago, x= 6( y - 15 )

x= 6y - 90 -------------2

Substituting value of x from equation 2 in equation 1, we get

6y - 90 - y = 25

5y -90 = 25

5y = 25+90

5y= 115

y= 23

Therefore son's age is 23 years and from equation 1 we get x= 25+y = 25+23 = 48 years. So father's age is 48 years.

How yo illustrate the information?

It should be noted that because the business is using the allowance approach in this instance, the write-off entry would not be to the account for bad debts. To write off an account, a debit must be made to a separate account that is kept as an allowance for dubious accounts.

Answer:

  2x +y = 1

Step-by-step explanation:

You want the equation of a line parallel to 2x+y=4 through point (-1, 3).

A parallel line will have the same slope, which is a function of the ratio of the x- and y-coefficients. Hence, the equation of the parallel line can use the same coefficients. It will have a constant suitable for the given point.

  given: 2x +y = 4

  parallel: 2x +y = c

  through point (-1, 3): 2x +y = 2(-1) +(3) = 1

The equation of the parallel line is 2x+y = 1.
