A. The hours taken to travel x miles at  per hour
B. The hours taken to travel 49 miles
C. The miles traveled in x hours at  per hour
D. The miles traveled in 49 hours

Solve the problem.Write an equation in standard form of the parabola that has the same shape as the graph of f(x) = 11x2, but which has its vertex at (3, 9).

A. f(x) = 11(x - 3)2 + 9 B. f(x) = 11(x + 3)2 + 9 C. f(x) = 11(x + 9)2 + 3 D. f(x) = (11x + 3)2 + 9

Find y:

16 8 ÄÄÄÄÄÄ + ÄÄÄÄÄÄ = 3 2y + 2 2y + 2 a. y = 2 b. y = 3 c. y = 4 d. y = 6 e. y = 8

Provide an appropriate response.What does the graph of the equation  look like?

A. The yz-plane B. The x-axis C. The y-axis D. The xz-plane
