Answer:

n³ - 3

Step-by-step explanation:

Let the number be n

Then 3 subtracted from the cube of a number:

The statement "If x = -2, then 2x = -4" can be demonstrated using the Multiplication Property of Equality.

Option C is the correct answer.

We have,

The Multiplication Property of Equality states that if you multiply both sides of an equation by the same non-zero number, the equality still holds true.

In this case, x = -2.

Multiply both sides of the equation by 2,

2x = 2(-2) = -4

Thus,

The statement "If x = -2, then 2x = -4" can be demonstrated using the Multiplication Property of Equality.

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 270°

a point (x, y ) → (y, - x ) , thus

C)- 8, - 4 ) → C'(- 4, 8 )

D(0, - 4 ) → D'(- 4, 0 )

E(- 8, - 9 ) → E'(- 9, 8 )

Answer:

A = 19.1°

B = 95.5°

C = 65.4°

Step-by-step explanation:

B = 5A

C = 4A-11

We know that a triangle has a total of 180° so:

180 = A + B + C

Which can be written as:

180 = A + (5A) + (4A - 11)

180 = 10A - 11

10A = 191

A = 19.1°

With A, we can work out B and C:

B = 5(19.1)

B = 95.5°

C = 4(19.1) - 11

C = 76.4 - 11

C = 65.4°

only A and E are true

Answer:

the answer 6.5

........

The distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

It is given that:

Two points are:

R(0, 1) and S(6, 3.5)

To find the distance between points R and S we can use the distance formula.

[tex]\rm d=\sqrt{(6-0)^2+(3.5-1)^2}\\[/tex]

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

d = √(36 + 6.25)

d = √42.25

d = 6.5 units

Thus, the distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.

Answer:

4x =16

a - 11 =12

9/10x + 6 =51

3(1/3 + 8) =11

Step-by-step explanation:

It Is Going To Be 5 Because 15÷3=5 And 15÷5=3 And 5×3=15 3×5=15

The required solution to the equation 5p - 9 = 2p + 12 is p = 7, as of the given condition.

To solve the equation 5p - 9 = 2p + 12, we will follow these steps:

Combine like terms on each side of the equation:

5p - 9 = 2p + 12

Move all the terms containing "p" to one side and the constant terms to the other side. To do this, we'll subtract 2p from both sides and add 9 to both sides:

5p - 2p - 9 + 9 = 2p + 12 - 2p + 9

Simplifying both sides:

3p = 21

Now, to solve for "p," we'll divide both sides of the equation by 3:

3p/3 = 21/3

Simplifying:

p = 7

Therefore, the solution to the equation 5p - 9 = 2p + 12 is p = 7.

Answer:

I would find the area of the circle and then find the area of the shape in the middle and then minus that from the area of the whole circle

Answer:

Step-by-step explanation:

1. Find the area of the circle. Area_c = pi * r^2

2.Find the area of the pentagon in terms of the radius Area_P =

3 sqrt(3) r^2 / 2

The answer you want is Area_shade = Area_c - area_P

Area = pi * r^2 - 3 sqrt(3)r^2/2

Answer:

The slope of a line characterizes the direction of a line.

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. also You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Let's flip the equation so x is on the left. We want to isolate x to see what it equals.

We subtract 3 from both sides.

4x=-16

We divide both sides by 4.

x=-4.
