Logarithm properties:
![\displaystyle \log_a b+\log_a c=\log_a (b\cdot c)\\\\\log_ab-\log_a c=\log_a \left( \frac{b}{c} \right)\\\\\log_{a^p}b^q= \frac{q}{p} \log_a b](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clog_a%20b%2B%5Clog_a%20c%3D%5Clog_a%20%28b%5Ccdot%20c%29%5C%5C%5C%5C%5Clog_ab-%5Clog_a%20c%3D%5Clog_a%20%5Cleft%28%20%5Cfrac%7Bb%7D%7Bc%7D%20%5Cright%29%5C%5C%5C%5C%5Clog_%7Ba%5Ep%7Db%5Eq%3D%20%5Cfrac%7Bq%7D%7Bp%7D%20%5Clog_a%20b)
According to this, we can get:
The score of Raven is 9 points
<em><u>Solution:</u></em>
Let the point scored by bangal be"x"
Score of Raven = 40 points
Given that,
The ravens scored 13 more than three times number points that the bangals scored in their last game
Score of raven = 13 + 3(score of bangal)
40 = 13 + 3x
Solve the above equation for x
3x = 40 - 13
3x = 27
x = 9
Thus the score of Raven is 9 points
Answer:
x - 6
Step-by-step explanation:
(4x2 + x - 5) - (5x2 - 1)
According to the order of operations, parenthesis come first so we will solve what is in the parenthesis first.
Then we do the multiplication because it comes before addition and subtraction.
4x2 = 8
Now we have 8 + x - 5
Combine like terms and 8-5=3 so we have 3 + x
Now for the second one.
5x2=10
10-1=9
Subtracting this from the first expression we have:
3+x-9 =
x - 6
Percent decrease. 41%
percent change= (new-old)/old *100
= -41 % the negative means decreasing
