The graph below represents the speeds of Kael and Lynn as they run around a track. A graph titled The Running Track. The horizontal axis shows time (minutes) and the vertical axis shows speed (m p h). Two lines begin at 0 speed in 0 minutes. The line labeled Lynn goes to 3 m p h in 8 minutes, to 12 m p h from 13 to 28 minutes, to 0 m p h in 40 minutes. The line labeled Kael goes to 10 m p h from 12 to 20 minutes, to 2 m p h in 32 minutes, to 0 m p h in 40 minutes. For how many minutes did Lynn run at a greater speed than Kael? 12 17 23 28

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0

Solve each quadratic equation by factoring and using the zero product property. [tex]x^2+6x+8=0[/tex]

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
