<span>if point A( 2,2) is reflected across the line Y then the new position A' is (-2,2) and the distance AY = distance A'Y if A is reflected across line R it is now at point B and the distance AR = distance BR lets say the point A(2,2) was perpendicular to the line R at the point (1, 4) then when reflected the point A now at location B will have coordinates</span><span>when flipped over a line of reflection the lengths are still the same the point to the line of reflection is the same length as the line of reflection to the reflected position the distance from the original point to the reflected point is twice the distance from the original point to the line of reflection cannot see your polygon. here is an example

How do I solve -5x+2y=6
Olegator [25]
Answer:  x = (2 y)/5 - 6/5 ,  y = (5 x)/2 + 3

Solve for x:
2 y - 5 x = 6
Subtract 2 y from both sides:
-5 x = 6 - 2 y
Divide both sides by -5:
Answer:  x = (2 y)/5 - 6/5
Solve for y:
2 y - 5 x = 6
Add 5 x to both sides:
2 y = 5 x + 6
Divide both sides by 2:
Answer:  y = (5 x)/2 + 3

Hello again! I need help with this question!
otez555 [7]

Answer:

(f o g) = -5x+22

Step-by-step explanation:

f o g  basically means f(g(x))

So:

f(g(x)) = -5(x-4)+2

f(g(x)) = -5x+20+2

f(g(x)) = -5x+22

Therefore: (f o g) = -5x+22

This is called function composition. Basically, the output of g(x) goes into the input of f(x).

How do I do this as I need help but don’t know how to solve it ??
Nina [5.8K]

Answer: 14 tickets weren't sold.

Step-by-step explanation:

14 times 15 = 210

So there are 210 seats in the cinema.

The total is $1274 so you would divide

6.50\sqrt{1274 \\ which equals 196

Your final step is to subtract

210 (the total seats) minis 196 (seats sold) equals 14 seats not sold

HOPE THIS HELPED!!!!

I’m not sure this I’m so confused in algebra
NARA [144]
|x+4| = 3x - 5

x + 4 = 3x - 5
2x = 9
  x = 9/2

-(x+4) = 3x - 5
-x -4 = 3x - 5
   4x = 1
     x = 1/4

answer
x = 1/4
x = 9/2
