Keisha is making a table summarizing her notes about the different types of investigation. She places an X into the table to show which steps are included in a descriptive investigation. Part of the table is shown. Where should Keisha place an X?

Can you draw an isosceles triangle with only one 80 degree angle?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

The vertex of this parabola is at (-2,-3). when the x-value is -1, the y-value is -5. what is the coefficient of the squared expression in the parabola's equation?
