From what I recall, just set both the equations equal to each other
6x=5x+7
6x=5x+7
-5x -5x
1x=7
x=7
Then just plug in what you found.
y=6(7)
y=42
y=5(7)+7
y=35+7
y=42
42=42
Thus, you know your answer is correct.
The formula for exponential form is:
e^x = y
Where, y in this case is 1800, e is exponential, and we
are to find e^x.
e^x = 1800
To find for x, we have to multiply both sides with the
natural log, ln.
ln (e^x) = ln (1800)
x ln e = ln (1800)
<span>ln e = 1 and by using
the calculator,</span>
x = 7.496 = 7.5
<span>Therefore the exponential form of 1800 is e^7.5</span>

Answer:
The second store (10 songs for $9)
Step-by-step explanation:
15 songs/$12 = $1.25 per song
10 songs/$9 = $1.11 per song
=(3x2 + 2x + 4) - (x2 + 2x + 1)
Combine like terms
=(3x2-x2)+(2x-2x)+(4-1)
=2x2+0+3
The 2x terms cancel each other to 0
=2x2+3
C) 2x2+3 is the answer.
Hope this helps!
