First I subtract the 3, then if you have 3 left and you take away 2/5 you're left with 2 3/5. hope this helped
Y- (5+0)= 2+3(x-2)
Y-5=6(x-2)
y-5=6x-2
+5 +5
y=6x+7
6x+7=x-2
-x -7 -x -7
5x=9
9/5
the answer is 1.8
A) -2
Explanation on pictures
For step 3 where it says Simplify the only thing it has is -2
A couple of rules to review:
#1). Ln(the square root of a number) = 1/2 Ln(the number)
and
#2). e^(Ln of a number) = the number
Now we're all set to solve this thing.
=======================================
<u>Ln( square root of(x+2) ) = 3</u>
From Rule #1: 1/2 Ln (x+2) = 3
Multiply each side by 2: Ln (x+2) = 6
From Rule #2: (x + 2) = e^6
(x + 2) = 403.43 (rounded)
Subtract 2 from each side: <em> x = 401.43</em> (rounded)
