Help me please In the following problems, two 0
Find the third
11. vertex (4,2); directrix y = - 3
12. directrix y = 2; vertex
13. vertex (-2,1); focus (2,1)
14. focus (-3, - 1); vertex

Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4? a.)y-3 = 1/16 (x-2)^2 b.)y+3 = -1/16 (x+2)^2 c.)x-2 = 1/16 (y-3)^2

Which represents the solution set of the inequality 5x-9 < 21? a. x < 12/5 b. x > 12/5 c. x > 6 d. x < 6

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
