Answer:
A
Step-by-step explanation:
Lets find the values:
<em>Gained</em><em> </em>2.2 kg = 2.2
<em>Lost</em><em> </em>1.5 kg = (-1.5)
<em>Lost</em><em> </em>3.7 kg = (-3.7)
Adding these would be represented by the equation:
2.2 + (-1.5) + (-3.7) = ?

Step-by-step explanation:
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>

Explanation:
An equality can be transformed in a system of equations by making each side equal to a new variable. In this case the variable y was made equal to each side.
See that may find the solution of such system by graphing both functions in a same coordinate system, where the intersection of the functions would show the solution of the system.
I show you that in the attached image. In such graph, the red curve is the function y = x² and the blue function is y = x³ + 2x.
The intersection point is (0,0) meaning that the solution is x = 0, y = 0.
