You can't get to quadrant 4 to quad 2 without 2 steps. The answers tell you that. The question is, did you use a reflection and a y or x translations or 2 reflections or 2 y or 2x translations.

Argument
You can take one point and see if it translate from beginning (purple triangle) to (yellow triangle) end. If two conditions will get you the right answer, then you have to try another point to break the tie.

We'll use Point C.
Choice A: If you reflect C over the y axis, you will go from (-5,1) to (5,1)
                 If you move C six units down, you will go from (5,1) to  (5,-5) which is where C' is.
                 That is pretty much the answer.

I could confirm it with another point which is the way your should do it.

Try Point A

Choice A:  Point A reflects across the y axis going from (-3,4) to (3,4)
                 Point A  translates down by moving from (3,4) to (3,-2) to become A'

Answer reflection and translation  in condition A

More Comment
I should do one more for you to show you that it is wrong.
You can try Choice B of the multiple Choice answers.

We will use Point C 
If we translate C across the x axis it will go from (-5,1) to (-5,-1)
The we are to translate 1 unit up. We will go from (-5,0) from (-5,-1) That's nowheres near where C' is. Choice B is wrong.

Answer:

160 m²

384 m²

Step-by-step explanation:

The area of a trapezium is given by :

A = 1/2(a + b)h

h = height ; a and b = lengths

From the diagram :

A = 1/2(12 + 20)10

A = 1/2(32)10

A = 16 * 10

A = 160 m²

2.)

Area of parallelogram = base * height

Base = 24 ; h = 16

A = 24 * 16

A = 384 m²

PERSON GETS 15 POINTZ PLZ HURRY The mean of the list n, n + 3, n+4, n+5, n+6, n+8, n+10, n + 12, n+15 is 11. What is the median?
7nadin3 [17]

Answer:

10

Step-by-step explanation:

To find the value of n we can write:

(n + n + 3 + n + 4 + n + 5 + n + 6 + n + 8 + n + 10 + n + 12 + n + 15) / 9 = 11

(9n + 63) / 9 = 11

9n + 63 = 99

9n = 36

n = 4

The median is n + 6 which is 4 + 6 = 10.
