For this question you can say:
log(x-2) - log(x+1) = -1
and you should know that log(x-2) minus log(x+1) is equal to:
log((x-2)/(x+1))
so now you have:
log((x-2)/(x+1)) = -1
now you can say:
(x-2)/(x+1) = 10^ -1 or (x-2)/(x+1) = 1/10
now you can say:
10(x-2) = x+1
10x -20 = x +1
10x - x = 20+1
9x = 21
x = 21/9
x = 7/3 :)))
I hope this is helpful
have a nice day
<span>1 12 f(x) = g(x)
or 112*(</span>14x3 + 28x2 – 46x )= <span>2x + 7
and </span>112*(42 +56 – 46x )= <span>2x + 7
</span>112*(98 – 46x )= <span>2x + 7
</span>and 10.976- 5.152x=2x+7
and -5.152x-2x=7-10.976
we have -5.154x= -10.969
and x= 10.969/5154
Have fun
<span>7/10 = 0.7
hope it helps</span>

Answer: 108 degrees</h3>
Work Shown:
Let x and y be supplementary angles, which means they add to 180 degrees.
x = 72 is one of the angles. We don't know the other angle yet, so lets just keep it at y.
x+y = 180
72+y = 180 ..... plug in x = 72
72+y-72 = 180-72 ..... subtract 72 from both sides
y = 108
The answer should be 9:15
