Answer:

10x-5

Step-by-step explanation:

Just multiply 5 by 2 and you get 10x and then multiply 5 by 1 which is 5 and use the minus symbol in the expression

so 10x-5

Answer:

5

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

Answer:

remember it starts with 3.14 r3 d 3.14 = 9.14 hope this helps but always start with 3.14 then multiply with the circumfederance and diameter

Step-by-step explanation:

1.

radius = 3 m

diameter = 3 × 2 = 6 m

formula = π × d

circumference = π × 6 = 18.85 m

2.

radius = 18 ÷ 2 = 9 cm

diameter = 18 cm

formula = π × d

circumference = π × 18 = 56.55 cm

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:

a = 45

Step-by-step explanation:

Start by changing the fractions so they share a common denominator to combine like-terms:

6/10a - 5/10a = 9/2

1/10a = 9/2

Multiply both sides by 10 to isolate a.

a = 90/2

a = 45

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

3 = x

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:

c on edge

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:

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

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.

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:

-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
