Answer:

f(x) = (x + 6)(x – 2)

Step-by-step explanation:

The roots of a polynomial are the solutions to its factors. This means you can set the factors equal to 0 and the roots are the solution. Working backwards, if the roots are x = -6 and x = 2 then they must have resulted from factors x + 6 and x - 2. This is true since x + 6 = 0 has solution x = -6. And x-2 = 0 has solution x = 2.

So the polynomial has factors (x+6)(x-2). The solution is f(x) = (x + 6)(x – 2).

Which system of equations can be graphed to find the solution(s) to 4x2 = x2 + 7?

Darina [25.2K]

Answer:

See explanation

Step-by-step explanation:

To solve the equation $4x^2 =x^2+7$ graphically, we need to consider left and right parts of this equation separately.

Left side gives us the function $y=4x^2.$ The graph of this function is shown with green curve in attached diagram.

Right side gives us the function $y=x^2+7.$ The graph of this function is shown with blue curve in attached diagram.

The x-coordinates of the points of their intersections are the solutions to the equation $4x^2 =x^2+7$

From the graph you can see that the solutions are

$x_1\approx -1.528\\ \\x_2\approx 1.528$

What is the return on equity for a firm with 15% return on assets, 10% return on debt, and a .75 debt/equity ratio?

Harman [31]

The return on equity for the firm is 18.75%.

<h3>Return on equity</h3>

Return on equity=Return on assets +[ (Debt/Equity ratio)×(Return on assets-Return on debt)]

Let plug in the formula

Return on equity=.15+ [(.75)× (.15-.10)]

Return on assets=.15+ (.75×0.05)

Return on assets=.15+0.0375

Return on equity=0.1875×100

Return on equity=18.75%

Therefore the return on equity ratio is 18.75%.
