Answer:

The Distributive Property states that when a number in parentheses is next to a number, you distribute the number outside of the parentheses and multiply by each of the numbers in parentheses.

Answer:

The length of the missing segment is 44

Step-by-step explanation:

Given

The figure above

Required

Determine the missing segment

Let the missing segment be represented with x

Given that, there exist parallel lines between the two triangles;

The relationship between the sides of the triangles is as follows;

[tex]\frac{20}{x} = \frac{10+20}{22+x}[/tex]

[tex]\frac{20}{x} = \frac{30}{22+x}[/tex]

Cross Multiply

[tex]20 * (22 + x) = 30 * x[/tex]

Open bracket

[tex]20 * 22 + 20 * x = 30 * x[/tex]

[tex]440 + 20x = 30x[/tex]

Subtract 20x from both sides

[tex]440 + 20x - 20x= 30x- 20x[/tex]

[tex]440 = 30x- 20x[/tex]

[tex]440 = 10x[/tex]

Divide both sides by 10

[tex]\frac{440}{10} = \frac{10x}{10}[/tex]

[tex]\frac{440}{10} = x[/tex]

[tex]44 = x[/tex]

[tex]x = 44[/tex]

Hence, the length of the missing segment is 44

Answer:

(-2, 0), (-1, 0), (1, 0), (2, 0)

Step-by-step explanation:

The x-intercept of function can be defined as the values of x at which the graph of the function intercepts the x-axis, or where the values of the function, y, is equals to zero.

As it is already given that the graph crosses x-axis at points (-2, 0), (-1, 0), (1, 0), and (2, 0), and as we know that the point where the graph crosses x-axis has the value of the function equal to zero, so the x-intercepts of the given function are (-2, 0), (-1, 0), (1, 0), and (2, 0)

Answer:

x = -3 and x = 1/2

Step-by-step explanation:

To find the solutions to

2x² + 5x - 3 = 0

we can use the quadratic formula, as follows:

[tex] x = \frac{-b \pm \sqrt{b^2- 4(a)(c)}}{2(a)} [/tex]

[tex] x = \frac{-5 \pm \sqrt{5^2- 4(2)(-3)}}{2(2)} [/tex]

[tex] x = \frac{-5 \pm 7}{4} [/tex]

[tex] x_1 = \frac{-5 + 7}{4} [/tex]

[tex] x_1 = 0.5 [/tex]

[tex] x_2 = \frac{-5 - 7}{4} [/tex]

[tex] x_2 = -3 [/tex]

Answer:

C & D & E

Step-by-step explanation:

The correct options are C, D, and E.

A scaled copy is an enlarged image of the previously given figure.

A scale factor is a factor by which the image is been enlarged. for example, the scale factor of 10 means each side will be multiplied by 10, resulting in a figure that is 10 times the real figure.

As given in the problem the scale factor is anything greater than 1.

We know that when we multiply 11 by 1 or a number greater than 1 the value will be the same or changed.

Therefore, the height of the scaled copy of the triangle will be anything equal to 11 or greater than 11.

Looking at the options available,

(A) 3 1/3 units

It is less than 11, therefore, not the right option.

(B) 10.5 units

It is less than 11, therefore, not the right option.

(C) 11.1 units

It is greater than 11, therefore, can be the possible option.

(D) 18 units

It is greater than 11, therefore, can be the possible option.

(E) 35 1/2 units

It is greater than 11, therefore, can be the possible option.

Thus, the correct options are C, D, and E.

Answer:

The length of the missing segment is 24

Step-by-step explanation:

Given

The figure above

Required

Determine the missing segment

Let the missing segment be represented with x

Given that, there exist parallel lines between the two triangles;

The relationship between the sides of the triangles is as follows;

[tex]\frac{15}{x} = \frac{15+5}{8+x}[/tex]

[tex]\frac{15}{x} = \frac{20}{8+x}[/tex]

Cross Multiply

[tex]15 * (8 + x) = 20 * x[/tex]

Open bracket

[tex]15*8 + 15 * x = 20 * x[/tex]

[tex]120 + 15x = 20x[/tex]

Subtract 15x from both sides

[tex]120 + 15x -15x= 20x-15x[/tex]

[tex]120 = 20x-15x[/tex]

[tex]120 = 5x[/tex]

Divide both sides by 5

[tex]\frac{120}{5} = \frac{5x}{5}[/tex]

[tex]\frac{120}{5} = x[/tex]

[tex]24 = x[/tex]

[tex]x = 24[/tex]

Hence, the length of the missing segment is 24

Answer:

The inverse is 4x+48

Step-by-step explanation:

y = 1/4x - 12

Exchange x and y

Solve for y

x = 1/4y -12

Add 12 to each side

x+12 = 1/4 y -12+12

x+12 = 1/4y

Multiply each side by 4

4(x+12) = 4*1/4y

4x+48 = y

The inverse is 4x+48

Answer:

4x + 48

Step-by-step explanation:

f(x) = 1/4x-12

y = 1/4x - 12

Switch variables.

x = 1/4y - 12

Solve for y.

x = 1/4y - 12

Add 12 on both sides.

x + 12 = 1/4y - 12 + 12

x + 12 = 1/4y

Multiply both sides by 4/1.

4/1(x + 12) = 1/4y × 4/1

4x + 48 = y

Answer:

contaminated

Step-by-step explanation:

The word fouled is used in the "The grapes of wrath"

where in writer says that "the water fouled the ignition wire and water fouled the carburetors".

In this context fouled means that some impurity is being added to the carburetor and wire frames.

Hence the best suitable word from the option will be "contaminated".

Contamination means " the act of making anything impure "

The law used to simplify the expression is quotient of powers.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression, 3¹⁰ / 3⁴, we need to determine the law used to simply the expression,

3¹⁰ / 3⁴

For this case we have an expression formed by a division of powers of the same base in which we must apply a law to simplify said expression.

By the definition we have the property of the power quotient of the same base set:

xᵃ / xᵇ = x⁽ᵃ⁻ᵇ⁾

So, using the same,

3¹⁰ / 3⁴ = 3⁽¹⁰⁻⁴⁾ = 3⁶

Thus, to simplify the expression we must use the property of the power quotient of the same base.

Hence, the law used to simplify the expression is quotient of powers.

Answer: 51

Step-by-step explanation:

Answer:

Step-by-step explanation:

P = 2w + 2l

l = 3 + w

38 = 2w + 2(3 + w)

38 = 2w + 6 + 2w

38 - 6 = 4w

32 = 4w

w = 32 : 4

w = 8 inches

l = 3 + w

l = 3inches + 8inches

l = 11 inches

Answer: 46

Step-by-step explanation:

Given that the coordinates of the quadrilateral-shaped property are G(–8, 3), A(4, 8), R(10, 0), and D(–2, –5).

You need to find length GA, GD, RA and RD by using the formula

L = sqrt[ ( X2 - X1)^2 + ( Y2 -Y1 )^2 ]

Length GA will be

L = sqrt [ ( 8-3 )^2 + ( 4+8 )^2 ]

L = sqrt ( 5^2 + 12^2 )

L = sqrt(25 + 144)

L = sqrt (169)

L = 13.

Length GD will be

L = sqrt [ ( -5-3 )^2 + ( -2+8 )^2 ]

L = sqrt ( -8^2 + 6^2 )

L = sqrt(64 + 36)

L = sqrt (100)

L = 10.

Length RA will be

L = sqrt [ ( 10-4 )^2 + ( 0-8 )^2 ]

L = sqrt ( 6^2 + 8^2 )

L = sqrt(36 + 64)

L = sqrt (100)

L = 10.

Length RD will be

L = sqrt [ ( 10+2 )^2 + ( 0+5 )^2 ]

L = sqrt ( 12^2 + 5^2 )

L = sqrt(144 + 25)

L = sqrt (169)

L = 13.

The perimeter P will be

Substitute all the parameters into the formula below

P = GA + GD + RA + RD

P = 13 + 10 + 10 + 13

P = 46

Answer:

The correct option is:

The function is decreasing for all real values of x where x < 1.5.

Step-by-step explanation:

We are given a function f(x) which is a product of two linear polynomial as:

Now, we know that on multiplying the two linear polynomial we will obtain a quadratic polynomial.

So, the function f(x) will be represented as:

So, we will plot the graph of the function and check which statements about the function hold true.

1)

The function is increasing for all real values of x where x < 0.

This statement is false.

Since we get from the graph that function f(x) is decreasing for x<0.

2)

The function is increasing for all real values of x where x < –1 and where x > 4.

This option is incorrect as the function is decreasing for x<-1

whereas it is increasing for x>4.

3)

The function is decreasing for all real values of x where –1 < x < 4.

This option is incorrect.

Since, the function is both decreasing as well as increasing in the interval (-1,4).

4)

The function is decreasing for all real values of x where x < 1.5.

This option is correct.

Since it could be observed from the graph that the function is decreasing for x<1.5.
