MIA PLAYED A VIDEO GAME. SHE STARTED WITH 10 1/2 POINTS. IN THE FIRST ROUND, SHE EARNED 5 1/4 POINTS. SHE LOST 2 1/2 POINTS IN ROUND 2 AND SHE LOST ANOTHER 3 3/4 POINTS IN ROUND 3. WHAT WAS HER FINAL SCORE ?

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
