<h3>
Answer: E) y = -25/13</h3>
=========================================================
Work Shown:
Let x = log(y+2)
The given equation becomes
4x = 3x-log(13)
Solving for x leads to
4x-3x = -log(13)
x = -log(13)
Then substituting gets us
log(y+2) = -log(13)
log(y+2) = log(13^(-1)) .... use the rule that A*log(B) = log(B^A)
log(y+2) = log(1/13)
y+2 = 1/13 ................. used the rule if log(A) = log(B), then A = B
y = (1/13) - 2
y = (1/13) - (26/13)
y = (1-26)/13
y = -25/13 .... answer is choice E
For each step, the logs are the same base. The base doesn't matter. It can be base 10 or base 2 or base e. As long as the base stays consistent is all that matters. Also, the base cannot be 1, 0 or a negative number. The base can be any other real number.
Roberto scored 3 points in 2 soccer games. At this rate, how many points will he score in 10 games?
<u>What we know</u>
<em>Roberto scored 3 points in 2 soccer games.</em>
<em>Roberto played 10 soccer games.</em>
<u>How to solve</u>
<em>If we know that Roberto scored 3 goals in 2 soccer games, we can find out how many goals he scored in 10 soccer games.</em>
2 soccer games → 3 goals
4 soccer games → 6 goals
6 soccer games → 9 goals
8 soccer games → 12 goals
10 soccer games ⇒ 15 goals
Therefore, Roberto scored 15 goals in 10 soccer games.
