Given the directrix of y = 6 and focus of (0, 4), which is the equation of the parabola?
Oy=-
- 1x²+
Oy=-1x2 - 5
4
Oy = 2x2 + 5
Oy = 1x2 - 5
4

Timed***how else can the sequence for row 1 be written? notice: square a: 1 penny = 20 square b: 2 pennies = 21 square c: 4 pennies = 22 the sequence formed is geometric, with a1 = , and common ratio r = .

Solve the system by the elimination method. x + y - 6 = 0 x - y - 8 = 0 when you eliminate y , what is the resulting equation? 2x = -14 2x = 14 -2x = 14
