Mr. Washington's pond had a water level of 3 feet at the beginning of the month. Due to evaporation, the water level dropped one-half foot each week. The graph represents the water level over a period of time. Which equation describes this graph?

Question 1/3

y = - x + 3

y = 2x + 3

y = -2x + 3

y = x + 3

Question 2/3

Which of the following graphs represents the inequality below?

y ≥ 2x - 2

Write an equation in point slope form with a slope of 2 and passes through the given point.

Question 3/3

y - 0 = 2(x + 2)

y - 2 = 2(x + 0)

y + 2 = 2(x - 0)

y - 0 = 2(x - 2)

Question 1/3

The expression below describes the number of organisms in a population of bacteria that is undergoing exponential growth. In this expression, r is the amount of growth per time interval, x is the number of time intervals. What does a represent in the expression?

(1 + r)

The change in population after one time interval.

The initial size of the population.

The length of time in one time interval.

The final population after x intervals.

Which system of inequalities does the graph represent?

Question 2/3

y > 2x - 4y ≤ -x + 3

y ≤ 2x -4y ≥ -x +3

y < 2x - 4y ≥ -x + 3

y < 2x - 4y > -x + 3

Question 3/3

Two lines are drawn on a coordinate plane. Line 1 has the equation y = x - 2. Line 2 passes through the points (- 4, -10) and (8, 2). Select the statement that is true regarding the two lines.

Line 1 has the same y-intercept as Line 2.

Line 2 has a greater y-intercept than Line 1.

Line 1 has a greater rate of change than Line 2.

Line 2 has a greater x-intercept than Line 1.

Question 1/3

A bag contains 23 coins consisting of quarters and nickels. The total value of the coins is $4.15. Which system of equations can be used to determine the number of quarters, q, and the number of nickels, n, in the bag?

0.25q + 0.05n = 4.15q + n = 23

0.05q + 0.25n = 4.15q + n = 23

25q + 5n = 23q + n = 4.15

5q + 25n = 23q + n = 4.15

Question 2/3

If the formula for the perimeter of a rectangle is P = 21 + 2w, which is an equation solved for w?

Question 3/3

Which of the following statements shows a relationship that is correlated but not causal?

The number of tardies to class and the number of detentions received.

The season of the year and the number of water related inuries/deaths.

As the temperature rises, the more the mercury in a thermometer will expand and rise.

The larger the dimensions of a rectangular path, the more square footage.
