You can use the Angle-Side-Angle (ASA) Congruence Postulate to prove the triangles are congruent.
Answer:
mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
8 - direct variation Since the equation can be written in the form y=kx. , y varies directly with x and k. The constant of variation, k, is 3.25
9 - When solving for y, y=5x-9 so y doesn't vary directly with x.
y doesn't vary directly with x
10 - direct variation Since the equation can be written in the form y=kx, y varies directly with x and k. The constant of variation, k, is -2.4
