15 The value of the function f (2) is when = -5 and is when I = 3. What is the equation of the function?
O f () = + 20
O f (x) = 10 +35
O f(x)=11-20
O f () = -12-1

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

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
