Triangle ABC is reflected across the y-axis to form triangle A′B′C′. The coordinates of the vertices of the triangles are given below. Triangle ABC: A(2, 3) B(6, 7) C(4, 1) Triangle A′B′C′: A′(2, 3) B′(–6, 7) C′(4, 1) Make a conjecture about the coordinates of a figure and its image after a reflection across the y-axis.

If there is no real number solution to the quadratic equation x^2+2x+c=0 what is a possible value of c? 1 -2 0 3

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

Read the equations in the table below. then drag a description of the situation and a table to represent each equation. indicate whether each of the relationships is proportional or non-proportional.
