If the axis of symmetry is x=-1, the vertex will have x-coordinate -1.
The point (0, 5) cannot be the vertex. The friend is not correct.
_____
If the point (1, 5) is on the graph so is the image of that point when it is reflected across the axis of symmetry. That image point is (-3, 5). A parabola that goes through points (1, 5) and (-3, 5) will not go through point (0, 5).
9.725 would be the answer
The angles w and 80 are inscribed angles in the top left and bottom right corners respectively. They are opposite angles in this inscribed quadrilateral. Because they are opposite angles in the inscribed quadrilateral, they add to 180 degrees.
w+80 = 180
w+80-80 = 180-80
w = 100
Answer: Choice D
Answer:
11- All 0's are on the x and y planes
12- All positive points/numbers are where the x and y axis are both positive (Quadrant 1, 2, and 4)
13- All negative points/numbers would be wherever the x and y axis are negative (Quadrants 2, 3, and 4)
