The answer choices show the steps Isaac took to solve the following literal equation for y . In which step did Isaac make a mistake? $$5\left(x+4\right)+3y=4-2y$$ $$y\ =-x$$

Isaac used the Distributive Property to get 5x + 4 + 3y = 4 - 2y.

Isaac subtracted 4 from each side to get 5x + 3y = -2y.

Isaac subtracted 3y from each side to get 5x = -5y.

Isaac divided both sides by -5 to get y = -x.

Part B: What does the x-coordinate of the vertex represent?

the time it takes for the ball to reach its maximum height

the time it takes for the ball to hit the ground

Part C: What does the y-coordinate of the vertex represent?

the time it takes for the ball to reach its maximum height

the time it takes for the ball to hit the ground

Which describes the end behavior of the absolute value function? f(x) = -|x| + 3

As x approaches infinity, f(x) approaches negative infinity and as x approaches negative infinity, f(x) approaches positive infinity.

As x approaches infinity, f(x) approaches negative infinity and as x approaches negative infinity, f(x) approaches negative infinity.

As x approaches infinity, f(x) approaches negative infinity and as x approaches negative infinity, f(x) approaches negative 3.

As x approaches infinity, f(x) approaches negative infinity and as x approaches negative infinity, f(x) approaches 4.

Shauna is buying tickets for a group of baseball games. She wants tickets for at least 5 games. Each ticket for an afternoon game costs $17.50 and each ticket for an evening game costs $32. Shauna wants to spend no more than $250. Which system of inequalities can Shauna use to find the number of tickets she can buy?

x + y ≥ 5 and 250 ≥ 17.5x + 32y

x + y ≤ 5 and 250 ≥ 17.5x + 32y

x + y ≥ 250 and 5 ≥ 17.5x + 32y

x + y ≥ 250 and 5 ≤ 17.5x + 32y

Is the model a good fit for the data? Explain.

Yes; the data are distributed evenly around the line of fit.

No; the data are too far from the line of fit.

No; the data are too close to the line of fit.

Yes; the line of fit touches at least one point in the data set.
