The balance was $4400.25 before 4 years.
<h3>What is an Equation?</h3>
An equation is a mathematical statement formed when two expressions are equated using an equal sign.
The equations are useful in the determination of unknown parameters.
The equations are of various types, such as Trigonometric equations, and quadratic equations.
The balance of an investment account is $308.32
Let the balance 4 years ago was $x
Then the balance today is represented by x + 308.32
The current balance is $4708.57
The expressions can be equated to get the value of the balance 4 years ago.
x + 308.32 = 4708.57
x = 4708.57 - 308.32
x = $4400.25
The balance 4 years ago was $4400.25

Answer:
Step-by-step explanation:
f(x)=2-x
x=2-y
add y both sides, then subtract x from both sides
y=2-x or f(x)=2-x same thing
if the speed "s" of the current in a certain whirlpool is modeled by s = 300/d, where "d" is the distences from the center of the whirlpool. the true statement is: as you move closer to the center of the whirlpool, the speed of the current approaches infinity.hope this help
