Answer:

-b-12

Step-by-step explanation:

4b+7-5b-19

4b-5b+7-19

-b+7-19

-b-12

Answer:

-b-12

Step-by-step explanation:

The like terms is 4b and -5b since they both have b so you have to combine like terms. The coefficients are 4 and 5. Then you combine the rest of the like terms which are 7 and -19 and get 12. So once simplify you get the expression -b-12

Answer:

  x = 20°

Step-by-step explanation:

For questions like this, it is helpful to remember that an exterior angle is equal to the sum of the remote interior angles.

  110° = 2x + 70°

  40° = 2x

  20° = x

_____

Similarly, ...

  y = x + 70° = 20° +70°

  y = 90°

Answer:

Agree with Luke!

Step-by-step explanation:

The Chess Club has 8 members

Total number of outcomes = 8

A new captain will be chosen by randomly selecting the name of one of the members

Number of favorable outcome (captain) = 1

Probability  = Number of Favorable outcome / Total number of outcomes

Probability = 1 / 8

I don't agree with Leah.

I agree with Luke because.... The Chess Club has 8 members

Total number of outcomes = 8

A new captain will be chosen by randomly selecting the name of one of the members

Number of captains that will be chosen = 1

Probability  = Number of Favorable outcome / Total number of outcomes

Probability = 1 / 8

Step-by-step explanation:

Point A describes the context A) (2,16), If Amy works 2 hours,

she will earn $16.

An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.

Pair in Order = (x, y)

x is the abscissa, the distance measure of a point from the primary axis x

y is the ordinate, the distance measure of a point from the secondary axis y

Given, A point on a coordinate plane A(2, 16), The x-coordinate is the number of hours and the y-coordinate is the amount earned in dollars.

From this and the given options, we conclude that the correct option is

If Amy works 2 hours, she will earn $16.

Answer:

Step-by-step explanation:

Since both triangles are similar then see if two dimension match up, so 9 is like 45, therefore, they multiplied 9 x 5 to get 45, so the scale factor (number you multiply to get the new value) is 5, since it grew 5 times

The table be like

Mike age        kellie age

15                     19

20                    24

25                    29

Since Mike's sister, Kellie, is 4 years older than he is

And, Let m be Mike's age and let k be Kellie's age.

So here the equation be like

k = m + 4

Step-by-step explanation:

just took the quiz

The equation representing the circle A is (x – 4)² + (y + 5)² = 36.

A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.

The general equation of circle is given by equation

( x - h )² + ( y - k )² = r²

Where,  ( h, k ) is the centre and 'r' is the radius.

As, the circle has a shift of 4 units on the +x axis.

The circle has a shift of the 5 units on the -y axis.

As, the circle has a radius of 6 units from the graph.

So, (h,k) = (4, -5).

Substitute the values of (h,k) in the general equation of the circle.

( x - 4 )² + ( y - (-5) )² = 6²

( x - 4 )² + ( y + 5 )² = 36

Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.

Answer:

Step-by-step explanation:

see the image below

Step-by-step explanation:

The side that is adjacent to 60 degree and 90 degree is the shortest side.

If u know the hypoutnese you can divide it by 2 to find the shortest side. for example if the hypotenuse is 10 then the shortest side is 5

If you know the other leg you can simply just remove the entire radical and just keep the whole number to find the length of the shortest side.

The side that his the adjacent to the 30 degree and 90 degree angle is the second longest side of the triangle.

If u know the shortest side, just multiply the radical

[tex] \sqrt{3} [/tex]

to the whole number.

If you know the hypotunese, divide the hypotenuse by 2 and then multiply the radical to find the length of the second shortest side

Finally, the hypotunese is the largest side. It is the slanted side length that is adjacent to the 30 and 60 triangle.

If you know the shortest side, just multiply the side length by 2 to get the hypotenuse.

If you know the other leg, remove the radical and keep the who the number and multiply the whole number by 2.

E.x if the second longest side length is

[tex]5 \sqrt{3} [/tex]

Remove the radical so it becomes

[tex]5[/tex]

then multiply it by two to find the hypotunese.

[tex]5 \times 2 = 10[/tex]

Answer:

on 4x + 33 = 10x + 3, we could use inverse operation and move 10x to left side, which will create -6x+33=3. we could also use the same thing to 33 and get -6x=-30. if we divide -30 by -6, we would get 5

Step-by-step explanation:

4+33=10+3

4+33−33=10+3−33

Answer:

(3,-12)

x = 3, y = -12

Step-by-step explanation:

(1) y=x-15

(2) y=-4x

solve equation (1) for x:

add 15 to both sides

x=y+15

plug in x=y+15 into equation (2):

y=-4(y+15)

y=-4y - 60

5y = -60

y = -12

plug in y=-12 into equation (2):

-12 = -4x

= 12,828.95 million kh

Hence, the estimated amount of electricity consumed per person is 12,828.95 million kh

Answer:

By closure property of multiplication and addition of integers,

If [tex]x + \dfrac{1}{x}[/tex] is an integer

∴ [tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot \left (x + \dfrac{1}{x} \right )[/tex] is an integer

From which we have;

[tex]x^3 + \dfrac{1}{x^3}[/tex] is an integer

Step-by-step explanation:

The given expression for the positive integer is x + x⁻¹

The given expression can be written as follows;

[tex]x + \dfrac{1}{x}[/tex]

By finding the given expression raised to the power 3, sing Wolfram Alpha online, we we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot x + \dfrac{3}{x}[/tex]

By simplification of the cube of the given integer expressions, we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot \left (x + \dfrac{1}{x} \right )[/tex]

Therefore, we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )= x^3 + \dfrac{1}{x^3}[/tex]

By rearranging, we get;

[tex]x^3 + \dfrac{1}{x^3} = \left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )[/tex]

Given that  [tex]x + \dfrac{1}{x}[/tex] is an integer, from the closure property, the product of two integers is always an integer, we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3[/tex] is an integer and [tex]3\cdot \left (x + \dfrac{1}{x} \right )[/tex] is also an integer

Similarly the sum of two integers is always an integer, we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3 + \left(- 3\cdot \left (x + \dfrac{1}{x} \right ) \right )[/tex] is an integer

[tex]\therefore x^3 + \dfrac{1}{x^3} = \left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )= \left ( x + \dfrac{1}{x} \right) ^3 + \left(- 3\cdot \left (x + \dfrac{1}{x} \right ) \right )[/tex] is an integer

From which we have;

[tex]x^3 + \dfrac{1}{x^3}[/tex] is an integer.
