Derive the equation of the parabola with a focus at (4,3) and a directrix of y=13

you can't solve x because it is 2 linear equation and you only have one equation

3x + 4y -25 =0 represents the amount of change sianna should recieve

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

step-by-step explanation: hi!
