A figure has the following vertices: A(0,5), B(8,3), C(6,0). What are the vertices of the figure after a reflection across the y-axis?

(0, 5), (-8, 3), (-6, 0)

Step-by-step explanation:

(0, 5) reflected across the y-axis = (0, 5)

(8, 3) reflected across the y-axis = (-8, 3)

(6, 0) reflected across the y-axis = (-6, 0)

Since the reflection is across the y-axis, we have to switch all of the x-values signs from positive to negative to get them from the top right side of the graph (positive side) to the top left side of the graph (negative side).

The only exception in this case is with the x-value 0 because 0 can never be negative or positive and remains in the middle of the graph.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

x-3y=4
