x=4 because if you add 7 to 10 you get -2x-3=-14x then you add -2x to -14x and you get -3=-12 then you divide by -3 and -12 to get 4
Answer
First subtract: 13 1/2 - 7 1/3 = 37/6
Second simplify: 37/6 = 6 1/6
Answer:
you use the distance formula: square root of (x2-x1)^2 + (y2-y1)^2. it is a little hard to type the equation out so I reccomend you look up the distance formula and plug the given coordinates into it
16 times the square root of x:
16 * √x so f(x) = 16√x
