Mumz [18]

The maximum allowable recurring debt for someone with a monthly income of $54.875 is $4.39.

<h3 /><h3>Maximum allowable recurring debt:</h3>

Using this formula

Maximum allowable recurring debt=Ratio×Monthly income

Where:

Ratio=28/36

Monthly income=$54.875

Let plug in the formula

Maximum allowable recurring debt=(36%×$54.875)-(28%×$54.875)

Maximum allowable recurring debt=$19.755-$15.365

Maximum allowable recurring debt=$4.39

Inconclusion the maximum allowable recurring debt for someone with a monthly income of $54.875 is $4.39.

Artemon [7]

Answer:

StartFraction 2 plus or minus StartRoot (negative 2) squared minus 4(1)(negative 3) EndRoot Over 2(1) EndFraction

Step-by-step explanation:

General quadratic equation: ax^2 + bx + c

where a is the coefficient of the quadratic term, b is the coefficient of the linear term and c is the independent term. Here the equation is: x^2 – 2x – 3, so a = 1, b = -2 and c = -3

Quadratic formula:

$x = \frac{-b \pm \sqrt{b^2-4(a)(c)}}{2(a)}$

Replacing

$x = \frac{2 \pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}$
