Log Modeling

Solve for x:  log₆x + log₆(x-5) = 2

• √7

• 9

• 4

• none of these

log (x - 1) - log (x - 2) = log 5

• 7

• 4/9

• 9/4

• 1/7

ln(x+8) - ln (8) = 3

• 152.68

• 188.77

• 4.24

• 8.01

log₉(10)-log₉(x-3) =log₉(72)

• 81/16

• 113/36

• No Solution

• 92/15

HINT: Take the answer choices and put in for r. See what number will make the two sides equal!!!

• r = 10

• r = 0, r = 10

• r = 6

• r= -8, r = 10

Move the 8 to the other side then move the 4 by dividing by 4. Then use base 10 to write in exponential form to solve!!!!
