Answer:
1. y = (1/6)(x +5)^2 -4.5
2. y = (-1/20)(x -10)^2 +1
Step-by-step explanation:
For focus (p, q) and directrix y=r, the equation is ...
y = 1/(2(q-r))·(x -p)^2 +(q+r)/2
___
1. For (p, q) = (-5, -3) and r = -6, the equation is ...
y = 1/(2(-3-(-6))(x -(-5))^2 +(-3-6)/2
y = 1/6(x +5)^2 -4.5
___
2. for (p, q) = (10, -4) and r = 6, the equation is ...
y = 1/(2(-4-6))(x -10)^2 +(-4+6)/2
y = (-1/20)(x -10)^2 +1
10 hats because she bought 6-3=3 then 7 hats in total +3=10
x(3x - 2) = (3x + 1)(x - 2)
3x^2 - 2x = 3x^2 - 6x + x - 2
3x^2 - 2x = 3x^2 - 5x - 2
-2x = -5x - 2
-2x + 5x = -2
3x = -2
x = -2/3
hope this helped xx
Idk if this is right bc it’s just a guess but maybe 156 bc that’s 26x6
