Ellen drew a graph showing the solution to an inequality. A number line going from negative 1.25 to positive 0.75. An open circle is at negative 0.75. Everything to the left of the circle is shaded. Then she wrote four possible inequalities. 3.25 less-than 2.5 + r 3.25 greater-than 2.5 + r Negative 3.25 less-than negative 2.5 + r Negative 3.25 greater-than negative 2.5 + r Which inequality does Ellen’s graph show the solution to? 3.25 less-than 2.5 + r 3.25 greater-than 2.5 + r Negative 3.25 less-than negative 2.5 + r Negative 3.25 greater-than negative 2.5 + r

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
