Answer:
x = 6
Step-by-step explanation:
Using the rules of logarithms
• log x - log y ⇔ log ( )
• x = n ⇔ x =
Given
log(5x) - log(x - 3) = 1
log ( ) = 1, then
= = 10 ( cross- multiply )
10(x - 3) = 5x
10x - 30 = 5x ( subtract 5x from both sides )
5x - 30 = 0 ( add 30 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6

The slope of a line in standard form is given by -A/B do for this line we get -8/9. since parallel line have the same slope the answer to the question is -8/9 also
