Answer:
y = x + 7
y = (-x) + 2
X + 7 = (-x) + 2
X + X = 2 - 7
2x = (-5)
<h3>x = (-5)/2 </h3>
Putting the value of X in equation
Y = (-5/2) + 7
Y = (-5)/2 + 7/1
Equalising the denominator by Taking LCM
Y = (-5)/2 +14/2
Y = ( -5 +14)/2
<h3>Y = (9)/2 </h3>
yo sup??
mid point of circle=centre of circle
let centre be O(3,2)
and the point be P(-4,8) and the other point be Q(x,y)
by mid point formula
-4+x/2=3 and 8+y/2=2
x=10 and y=-4
therefore coordinates of the other point are (10,-4)
Hope this helps.
Answer:
15
Step-by-step explanation:
If CD and DE equal, then x+6 = 4x -21
So if you subtract x from both sides and plus 21 to both sides, that would be 3x = 27. Divide by 3 on both sides and you get 9.
Plug in x+6 with 9 and you get 15.

Answer: Choice C. (-1, -5)</h3>
Explanation:
The reflection rule we use is

when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.
Therefore,
