The number of brake pads needed for a car is 4, and a manufacturing plant has 480 brake pads. The number of brake pads
remaining after brake pads have been
installed on x cars is f(x) = 480 — 4x.

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

you first to choose the points and then move from then as the slope you have
