#9 is correct.
#10 is actually choice 2.
This is because the difference of logs with the same base (log(x)-log(y)) is equal to the log of the two numbers divided by each other, so log(x)-log(y) would equal log(x/y). In your case, log(15)-log(10) => log(15/10) => log(3/2), final answer.
Answer:
John need to get 293 in his next game to bring his average up to 183.
Step-by-step explanation:
John starts with N games played and averaging 177 points per game.
In game N+1, John scored 199 points.

So, John has now played (N+1) = 22 games.
We need to know what score John needs in game 23 to bring his average to 183.

Answer:
B. 12
Step-by-step explanation:
Answer:
m = -2/3
Step-by-step explanation:
m = slope

m = -3 -1/ 3 - (-3)
m= -4/ 6
m= -2/3
These two angles are a linear pair so they will add up to 180°
equation:
x+42=180
x=138°
