The easiest way to determine whether the point is on the circle:

  ⇒ plugging the values into the equation

    ⇒ then see if the equation holds true

       ⇒ meaning that the point is on the line

Step-by-step explanation:

x+ x+1+ x+2=126

3x+3=126

3x=126-3

3x=123

divide each side by 3

x=41

x+1=42

x+2=43

check your answer by adding the three integers:

41+42+43=126

Answer:

Step-by-step explanation:

let first integer= Y note : Y is an even number.

second integer= (Y+2)

third integer = (Y+4)

from the question,

Y+Y+2+Y+4= 126

3Y+6 = 126

3Y = 126-6

3Y = 120

dividingbothsides by (3)

3Y/3 = 120/3

Y= 40

therefore, the even integers are:

40

(Y+2)= 40+2= 42

(Y+4) =40+4= 44

Answer:

$115

Step-by-step explanation:

VAT = 15% of marked price

        = 0.15 * 100

        = $ 15

Price paid by the customer = 100 + 15

                                             = $ 115

If m is parallel to n then value of x and y is X = 41° and Y = 41°.

An angle is formed when two straight lines or rays meet at a common endpoint.

Given that line m and n are parallel lines.

Parallel lines are those straight lines that are always the same distance apart from each other.

As y is vertically opposite to the angle 41° . So the value of y is also 41°  and angle x is equal to angle y because they are alternate angles. So the value of y is also  41°.

Therefore X = 41° and Y = 41°.

Answer:

-1/2arctan(x) - 1/4ln|x + 1| + 1/4ln|x - 1| + C

Step-by-step explanation:

Answer:

Step-by-step explanation:

so to go forward we input x and get out y,   to go backwards ( the inverse) we plug in y and get out x   ,  so just solve the equation for x

f(x) = 8x - 5

remember that f(x) = y

so,

y = 8x - 5

now solve for x

y+5 = 8x

(y+5) / 8 = x

then remember that we want to swap x and y ,

(x+5) / 8 = y

now y = [tex]f^{-1}[/tex](x),  it's kinda confusing.

 [tex]f^{-1}[/tex](x)= [tex]\frac{x+5}{8}[/tex]

Step-by-step explanation:

3+4+1=11

4+4=11

4+4=11

4+4=11

4+4=11

4+4−4=11−4

4=7

44=7

"3 va después de 5 y entre 7 y 12" = "3 goes after 5, and between 7 and 12"

This eliminates A and D (3 is not between 7 and 12 in either choice).

"5 va antes de 12 y entre 7 y 3" = "5 goes after 12, and between 7 and 3"

This eliminates C (5 is not between 7 and 3).

So the correct sequence is B.

How do we write 8x-2y=10 in slope intercept form?

[tex]\blue\textsf{\textbf{\underline{\underline{Answer and Solution:-}}}}[/tex]

First subtract 8x on both sides:-

-2y=10-8x

or

-2y=-8x+10

Now divide by -2 on both sides:-

y=2x-5

This is our equation in slope intercept form.

[tex]\large{\boxed{\sf g(x) = \dfrac{1}{2} |x - 4| +7}}[/tex]

Explanation:

Absolute value of a graph formula:

Take two points: (4, 7), (6, 8)

[tex]\sf Find \ slope \ (a) : \sf \ \dfrac{y_2 - y_1}{x_2- x_1} \ = \ \dfrac{8-7}{6-4} \ = \dfrac{1}{2}[/tex]

Putting them together :  [tex]\bf g(x) = \dfrac{1}{2} |x - 4| +7[/tex]

Answer:

[tex]g(x)=\dfrac{1}{2}|x-4|+7[/tex]

Step-by-step explanation:

Translations

For [tex]a > 0[/tex]

[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]

[tex]f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}[/tex]

[tex]y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis by a factor of}\:a[/tex]

-----------------------------------------------------------------------------------------

Parent function:  [tex]f(x)=|x|[/tex]

(with vertex at the origin)

From inspection of the graph, the vertex of the transformed function is at (4, 7).  Therefore, there has been a translation of:

[tex]\implies f(x-4)+7=|x-4|+7[/tex]

From inspection of the graph, we can see that it has been stretched parallel to the y-axis:

[tex]\implies a\:f(x-4)+7=a|x-4|+7[/tex]

The line goes through point (0, 9)

Substituting this point into the above equation to find [tex]a[/tex]:

[tex]\implies a|0-4|+7=9[/tex]

[tex]\implies 4a=2[/tex]

[tex]\implies a= \dfrac{1}{2}[/tex]

Therefore,

[tex]\implies g(x)=\dfrac{1}{2}|x-4|+7[/tex]

y=5

Step-by-step explanation:

do equation 1 and 2 then,

subtract the equation

find the value of y by subtracting

and put the value of y in any equation and get the value of x

Step-by-step explanation:

4x+3y=21

4x+2y=16

If we add both the equation:

4x + 3y = 21

4x + 2y = 16

(-) (-) (-)

4x + 3y = 21

-4x - 2y= -16

=> 0+1y= 5

y=5

substituting Y in eq 1

4x+3y=21

4x+3(5)=21

4x+15=21

4x=21-15

4x=6

x=1.5
