You should know that you can predict changes in coordinates after translations without a graph or anything like that.

(x, y) reflected over the x axis = (x, -y)
(x, y) reflected over the y axis = (-x, y)
(x, y) rotated 90 degrees around the origin = (y, -x)
(x, y) rotated 180 degrees around the origin = (-x, -y)
(x, y) rotated 270 degrees around the origin - (-x, y)

So here's our set of points.
A(1, 2), B(4, 6), C(4, 6)

Here's those points reflected over the x axis.
A'(1, -2), B'(4, -6), C'(4, -6)

And here's <em>those</em> points rotated 180° around the origin.
A''(2, -1), B''(6, -4), C''(6, -4)

I think you made a mistake writing down the question, though, because B and C are the same yet you say ABC forms a triangle. You should be able to go through this process with whatever the coordinate was supposed to be.

Arada [10]

Answer: 7 Answers Incorrect

Step-by-step explanation:

86% may be written as (86/100) or as 0.86.

Since "it's a ratio (sic.) problem," then:

                 86/100 = correct/50

                correct = (86/100)*50       (multiply both sides by 50)

                correct = 43

And, 50-43 = 7 incorrect

Alexxx [7]

Step-by-step explanation:

1) -5x<35

we divide both sides by 5

-5x/5<35/5

-x<7

we divide both sides by-1 to remove the negative sign

-x/-1<7/-1

x<7/-1

2) 2x>-42

we divide both sides by 2

2x/2>-42/2

x>-21

3) x/3≤-7

we multiply by 3 and we cancel 3

3(x/3)≤3(-7) we cancel the 3

x≤-21

4) x/-4≥-4

we do the same thing

x≥1

(2000+100+10C+8) x 4 = 8000+100C+10+240C = 432-12 = 420
Therefore,

C = 7
So, the number is 2178.
