2. The rate of change is constant in the graph. Find the rate of
change. Explain what the rate of change means for the situation.
A-3; value drops $3 every year.
B-100; value drops $100 every year.
ec 100 value drops $100 every 3 years.
D-1; value drops $1 every year.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Drag the tiles to the boxes to form correct pairs. not all tiles will be used. match the circle equations in general form with their corresponding equations

The equations 2x-5y = -5 11x-5y = 15 9x+ 5y = 5 and 14x+ 5y = -5 are shown on the graph below. which system of equations has a solution of approximately (-0.6. 0.8)?
