Answer:

$4 \frac{1}{9}x$ + $12\frac{1}{3}$ = 0

Step-by-step explanation:

Based on 2x - 9y - 12 = 0

-9y = 12 - 2x

9y = -12 + 2x

y = $-1\frac{1}{3} + \frac{2}{9} x$

Therefore...

5x - 4y + 7 = 0

5x - 4( $-1\frac{1}{3} + \frac{2}{9} x$ ) + 7 = 0

5x + $5\frac{1}{3}$ - $\frac{8}{9} x$ + 7 = 0

$4 \frac{1}{9}x$ + $12\frac{1}{3}$ = 0

How can the indicated logarithm be found? Without a calculator❓

e-lub [12.9K]

I guess you're supposed to write the expression on the right in terms of $A,B,C$ .

18. Notice that $729=9^3$ , so

$\log_8729=\log_89^3=3\log_89=3B$

20. Notice that $\dfrac{14}3=\dfrac{42}9=\dfrac{6\times7}9$ , so

$\log_8\dfrac{14}3=\log_8\dfrac{6\times7}9=\log_86+\log_87-\log_89=A+C-B$
