Answer:
axis of symmetry: x = 2
see below for a graph
Step-by-step explanation:
You can complete the square to put the equation in vertex form.
y = (x^2 -4x +4) -1 -4
y = (x -2)^2 -5 . . . . . . vertex is (2, -5)
The equation of the axis of symmetry is the equation of the vertical line through the vertex:
x = 2 . . . . . axis of symmetry
__
Points on the graph are easily found by using integer values on either side of x=2. Points on one side of the axis of symmetry are mirrored on the other side of it.
<BOA = 360 -250 = 110
<<span>BDA = 110/2 = 55
<</span><span>BCA = 360 - (90+90+110)
</span><<span>BCA = 360 - 290

Answer:
-21 - (-14) = <u>-21</u> + <u>14</u> = <u>-7</u>
Step-by-step explanation:
A - and a - make a +. So -21 - (-14) makes -21 + 14. Solve to get -7.
Hope it helps!
