BC = 18

AB = AC, hence

8x - 4 = 5x + 11 ( subtract 5x from both sides )

3x - 4 = 11 ( add 4 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

BC = 4x - 2 = (4 × 5 ) - 2 = 20 - 2 = 18

All log graphs contain the points (1,0), (a,1), and (1/a,-1).<br><br> True .<br> False.

Bumek [7]

The correct answer is: True

Explanation:
1. $log_a1 = 0$ (Straightforward)
2. $log_aa = 1
$ (log to base of itself is always 1)
3. $log_a \frac{1}{a} = log_aa^{-1} = -1(1) = -1$ (Using log power property)

Hence the correct option is True.

Pipe A can fill a swimming pool in 12 h. Working with another Pipe B, it only takes 3h How long would it take Pipe B working al

MatroZZZ [7]

My guess is 9 hours, because since pipe a takes 12 hours and with pipe b it takes 9, it's 12-9=3 I think.
