If x represents a number, then what is an expression for a number that is eight less than twice the value of x.

Answer:

Decagon Definitions A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° 144 ° and they all add up to 1,440° 1,440 °.

Answer:

9.94

Step-by-step explanation:

y = [tex]\frac{1}{4}[/tex] x - 9

y - 2 = - 4(x - 3)

y = - 4x + 14

- 4x + 14 = [tex]\frac{1}{4}[/tex] x - 9

16x - 56 = - x + 36

17x = 92

x = [tex]\frac{92}{17}[/tex]

y = (-4) [tex]\frac{92}{17}[/tex] + 14 = - [tex]\frac{368}{17}[/tex] + [tex]\frac{238}{17}[/tex] = - [tex]\frac{130}{17}[/tex]

b. odd

Step-by-step explanation:

f(-x)^3-2x(-x)

f(-x)=-x^3+2x

f(-x)=-(x^3-2x)

f(-x)=-f(x)

The given function f(x) = x³ - 2x is an odd function.

Given that,
To determine whether the given function is odd, even, or neither.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The given function is f(x) = x³ - 2x,
For the given function to be odd f(-x) = -f(x)
put x = -x in the function,
f(-x) = (-x)³ - 2(-x)
f(-x) = -x³ + 2x

Thus. the given function f(x) = x³ - 2x is an odd function.

Step-by-step explanation:

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

[tex]2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17[/tex]

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

[tex]\angle1=2(17)+6\\\angle1=34+6\\\angle1=40[/tex]

So, the actual measure of ∠1 = 40°

Answer:

The first option is the correct answer.

Step-by-step explanation:

The graph would move to the right 3 units.

Answer:

In a tape diagram, each of the lengths represents a fixed quantity of something.

Let's suppose that each one of these lengths represents a distance d.

We also know that the expert trail is 750 meters longer than the beginner one.

And in the tape diagram, the expert trail has 3 more lengths than the beginner trail, then we must have that the difference in distance must be equivalent with the difference in lengths.

750m = 3*d

d = 750m/3 = 250m

Then each length in the tape diagram represents 250m

With this we can find the length of each trail.

The beginner trail has 1 length, then it is 1*250m = 250 meters long.

The expert trail has 4 lengths, then it is 4*250m = 1000 meters long.

Answer:

The perimeter of the isosceles triangle is 32 centimeters

Step-by-step explanation:

The perimeter of any figure is the sum of the lengths of outline sides

Let us use this fact to solve our question

∵ The perimeter of the triangle is the sum of the lengths of its 3 sides

∵ The triangle is an isosceles triangle

∵ The length of each two equal sides is 12 centimeters

∵ The length of the third side is 8 centimeters

→ Add the lengths of the 3 sides

∴ The perimeter of the triangle = 12 + 12 + 8

∴ The perimeter of the triangle = 32 centimeters

∴ The perimeter of the isosceles triangle is 32 centimeters

Step-by-step explanation:

Answer: x = 8

because  The upper triangle is an isosceles triangle (the two sides are equal)

=> 5x + 5 = 45°

<=> x = (45 - 5) : 5

<=> x = 40:5 = 8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

5x + 5 + 5x + 5 + 90 = 180, that is

10x + 100 = 180 ( subtract 100 from both sides )

10x = 80 ( divide both sides by 10 )

x = 8

Answer:

66 ft

Step-by-step explanation:

It is given that the windows on a building are proportional to size of the building.

Height of each window = 18 in

Width of each window = 11 in

Height of the building = 108 ft

Let the width of the building be x.

Since windows on a building are proportional to size of the building, therefore

On cross multiplication we get

Divide both sides by 18.

Answer:

66 ft

Step-by-step explanation:

What your doing is setting up a proportion that of the windows(18x11) dimensions and the buildings(108xW) dimensions.

So it would be 18/11=108/x

you would cross multiply so you would have 11x108 (1188)= 18x

Divide by 18 so x=66

The slope is the intensity of inclination thus the slope of p(x) is greater than the slope of m(x) thus option (A) is correct.

A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.

As per the given function,

p(x) = 157.1x

p(x)/x = slope = 157.1

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

In the function m(x) the slope will be as,

Slope = (188.4 - 125.6)/(3 - 2)

Slope = 62.8

Hence "The slope is the intensity of inclination thus the slope of p(x) is greater than the slope of m(x)".

Step-by-step explanation:

Since domain encompasses x values only, we are looking at the x-values of the graph. We see that our x-values span from -2 to 3. However, since x = -2 is a open dot, it is NOT included in the domain. Since x = 3 is a closed dot, it IS included in the domain:
