Formula to get the scale factor of any image from it's preimage,

Scale factor of an image = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the preimage}}[/tex]

From the figure attached,

F' is the image of preimage F after dilation.

Scale factor = [tex]\frac{\text{Length of A'B'}}{\text{Length of AB}}[/tex]

                    = [tex]\frac{4}{6}[/tex]

                    = [tex]\frac{2}{3}[/tex]

Therefore, Figure F has been dilated by a scale factor of [tex]\frac{2}{3}[/tex] to form F'.

Option (C). will be the answer.

Answer:

Option (C)

Step-by-step explanation:

In this question we will use the property " similarity of the triangles".

If DE and AC are parallel two triangles BED and BCA will be similar, corresponding sides of the triangles will be proportional.

[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]

Option (A).

[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]

[tex]\frac{22+12}{12}=\frac{14+26}{14}[/tex]

[tex]\frac{34}{12}=\frac{40}{14}[/tex]

[tex]\frac{17}{6}=\frac{20}{7}[/tex]

But [tex]\frac{17}{6}\neq \frac{20}{7}[/tex]

Therefore, given triangles are not similar.

AC and DE are not parallel.

Option (B).

[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]

[tex]\frac{25}{25-7}=\frac{21+9}{21}[/tex]

[tex]\frac{25}{18}=\frac{30}{21}[/tex]

[tex]\frac{25}{18}=\frac{10}{7}[/tex]

But [tex]\frac{25}{18}\neq \frac{10}{7}[/tex]

Therefore, AC and DE are not parallel.

Option (C).

[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]

[tex]\frac{22.5+15}{15}=\frac{40}{40-24}[/tex]

[tex]\frac{37.5}{15}=\frac{40}{16}[/tex]

2.5 = 2.5

Therefore, AC║DE.

Option (D).

[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]

[tex]\frac{17.5+5}{17.5}=\frac{20.4+6}{20.4}[/tex]

[tex]\frac{22.5}{17.5}=\frac{26.4}{20.4}[/tex]

[tex]\frac{9}{7}=\frac{22}{17}[/tex]

But [tex]\frac{9}{7}\neq \frac{22}{17}[/tex]

Therefore, AC and DE are not parallel.

Option (C) will be the answer.

Answer:

The value of u is 6

Step-by-step explanation:

The rule of the slope of a line is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] , where

[tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are two points on the line

Let us use this rule to solve the question

∵ The slope of the line is -3

∴ m = -3

∵ The two points on the line are (-5, u) and (-4, 3)

∴ [tex]x_{1}[/tex] = -5 and [tex]x_{2}[/tex] = -4

∴ [tex]y_{1}[/tex] = u and [tex]y_{2}[/tex] = 3

→ Substitute these values in the rule of the slope above

∴ [tex]-3=\frac{3-u}{-4-(-5)}[/tex]

∴ [tex]-3=\frac{3-u}{1}[/tex]

→ By using cross multiplication

∴ -3 × 1 = 3 - u

∴ -3 = 3 - u

→ Add u to both sides to move u from the right side to the left side

∴ -3 + u = 3 - u + u

∴ -3 + u = 3

→ Add 3 to both sides to move -3 from the left side to the right side

∴ -3 + 3 + u = 3 + 3

∴ u = 6

The value of u is 6

The answer is C because 6x and 6 are both in the line

Answer:

A. y=-2x+2

Step-by-step explanation:

A slope is also known as the gradient of a line. The slope of the line is 7/2.

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The two of the points that lie on the line are (0,0) and (4,14). Therefore,

The slope of the line is,

Slope, m = (14-0)/(4-0) = 14/4 = 7/2

Hence, the slope of the line is 7/2.

Step-by-step explanation:2x +6

Answer:

2x+6

Step-by-step explanation:

Definition - To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Other examples-

5(4x+5) -------> You would distribute(Multiply) 5 into 4x+5

5 times 4x is equal to 20

5 times 5 is equal to 25

The sign is addition

Thus, 20x+25

Step-by-step explanation:

The answer is a complex fraction division. The easiest way to do it is likely to convert both fractions to a decimal.

Answer:

B

Step-by-step explanation:

Given 2 sides then the third side x is

difference of 2 sides < x < sum of 2 sides , that is

28 - 16 < x < 28 + 16

12 < x < 44

Since 12 is less than x then shortest length = 13 cm → B

Answer:

f(x) = x³ + x² - 22x - 40

Step-by-step explanation:

Given that x = a is a zero of f(x) then (x - a) is a factor

Here the zeros are x =  - 4, x = - 2, x = 5 , then the factors are

(x + 4), (x + 2) and (x - 5)

The function is then the product of the factors, that is

f(x) = (x + 4)(x + 2)(x - 5) ← expand the first pair using FOIL

     = (x² + 6x + 8)(x - 5) ← distribute

     = x³ + 6x² + 8x - 5x² - 30x - 40 ← collect like terms

     = x³ + x² - 22x - 40
