After dilation by a scale factor of 2 we get the result (-8, 10).
What is the scale factor?
When describing a shape, you must be clear about how much it has been enlarged.
The ratio of two dimensions that causes one figure to be enormous and another to be little is known as the scale factor.
Given coordinate (-4, 5)
If any general coordinate (x, y) is scaled by 2 then we get
X= 2x and Y = 2y
Hence, X= 2 * -4, where x = -4
=> X= -8
and Y= 2 * 5, where y = 5
=> Y = 10
Therefore, the required result is (-8, 10).

Answer:
the answer is 52.
Step-by-step explanation:
because of the locations of the two angles, it can be concluded that 156=3x.
now you have an equation.
solve for x.
hope this helps ;)
Answer:
Only if there 10 students, which isnt likely
Step-by-step explanation:
If you observe the 4 graphical representations you will see that except stem and leaf plot, the rest 3 represent the same information.
As the time is increasing, the frequency of students who listen to music is decreasing. The frequency is maximum for the first group 0 - 1 and least for the last group 6 - 7.
The ranges shown in both Frequency Table and Histogram are the same.
So, the following options are correct:
<span>B) One of the displays does not show the same information as the others.
C) The first three displays show that as time increases, frequency decreases.</span>
Answer:
105 mm²
Step-by-step explanation:
The area (A) of the regular polygon is calculated as
A = 
pa ( p is the perimeter and a the apothem )
Here a = 5 and p = 6 × 7 = 42, thus
A = 
× 42 × 5 = 21 × 5 = 105 mm²
