Is Dn (triangle DEF) = triangle D'E'F' an enlargement or a reduction? What is the scale factor n of the dilation?
Answers
Answer:
A. Enlargement, 1.5
Step-by-step explanation:
Comparing the two triangles, it would be observed that ΔD'E'F' is larger than ΔDEF. This implies that ΔDEF has been multiplied by a scale factor.
To determine the scale factor used, consider the side DE and D'E' of the two triangles:
scale factor = [tex]\frac{D'E'}{DE}[/tex]
= [tex]\frac{6}{4}[/tex]
scale factor = 1.5
Therefore, ΔDEF was enlarged to ΔD'E'F' using a scale factor of 1.5. Then the correct option is A.

[tex]y = 4x - 9[/tex]

Answer:
y=4x+(-9)
Step-by-step explanation:
Slope intercept form is y=mx+b
m is the slope which can be found using rise/run. In this case 4/1=4 so m=4
b is the y intercept which is the y value where the line passes through the X axis. This also can be found as the Y value where X=0 if that is easier for you. In this problem y=-9 where X=0. Therefore b=-9.
Plug these values back into the equation and you get the equation of the line in slope intercept form. For this line that is y=4x+(-9).

D. g(x) = (x - 5)² + 3
Step-by-step explanation:
If a graph is translated horizontally, the value will affect x inside of the parentheses. For example, (x + #) or (x - #).
If a function is translated to the right, there will be a (-) sign. If a function is translated to the left, there will be a (+) sign.
This function needs to be translated 5 units to the right. Therefore, the equation will be: g(x) = (x - 5)² + 3
If £29 =500 rubles how many £ are in 1,260 give your answer to 2dp
Answers

Answers
Answer:
x = 20, ∠ A = 125°
Step-by-step explanation:
∠ A and ∠ B are Alternate interior angles and are congruent, so
∠ A = ∠B , substitute values
6x + 5 = 4x + 45 ( subtract 4x from both sides )
2x + 5 = 45 ( subtract 5 from both sides )
2x = 40 ( divide both sides by 2 )
x = 20
Thus
∠ A = 6x + 5 = 6(20) + 5 = 120 + 5 = 125°
Answer:
∠A = 125 degrees.

Answers
Answer:
x = - 2 ± [tex]\sqrt{11}[/tex]
Step-by-step explanation:
To solve the equation using the method of completing the square.
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
add ( half the coefficient of the x- term )² to both sides
x² + 2(2) x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\sqrt{11}[/tex] ← exact solution

Is 9.5 bigger than 9
Answers
Answer:
yes it is.
Step-by-step explanation:
9.5 is greater than 9 as when we divide 9.5 by 9 the result is greater than one.
What is the scale factor?By using a scale factor we can determine if one quantity is greater than or less than another quantity.
Given, are two numbers 9.5 and 9 to determine if 9.5 is greater than 9 or not we'll divide 9.5 by 9 if the result is greater than 1 then 8.5 is greater than 9 and if the result is less than 1 then 9.5 is less 9.
Now, 9.5/9 = 1.05 which is greater than 1.
∴ 9.5 is greater than 9.
