D.

f(x) can be written as (x+2)(x-2)(x-1)
by using difference of two squares to expand x^2 - 4 whch yields 3 x intercepts

similarly, k(x) can be written as
x(x+5)(x-5) which also yields 3
x intercepts (0,-5, and 5)

Spencer has a retirement account through his employer. His monthly contributions to the account are taken out of his check befor
abruzzese [7]

Answer:

Traditional 401 (K) plan

Step-by-step explanation:

The fact that the contributions to the pension plan are deducted before payroll taxes means that the plan in question is a traditional 401 (K) plan with taxes on the earnings deferred until the employee eventually withdraws funds from the pension plan.

This is quite different from Roth  401 (K) Plan where the contribution is not tax deferred ,instead contributions are made after payroll taxes have been sorted but eventual withdrawal from the plan is tax exempt.

What is the equation of the line passing through the points  (Two-fifths, StartFraction 19 Over 20 EndFraction)and  (one-third,
Vinil7 [7]
<h3>4x - 8y = -6 is the equation of line in standard form</h3>

<em><u>Solution:</u></em>

<em><u>The equation of line in point slope form is given as:</u></em>

y - y_1 = m(x-x_1)

Where, m is the slope of line

<em><u>The slope of line is given as:</u></em>

m = \frac{y_2-y_1}{x_2-x_1}

From given,

(x_1, y_1) = (\frac{2}{5} , \frac{19}{20})\\\\(x_2, y_2) = (\frac{1}{3} , \frac{11}{12})

<em><u>Substituting the values we get,</u></em>

m = \frac{\frac{11}{12} - \frac{19}{20}}{\frac{1}{3} - \frac{2}{5}}\\\\Simplify\\\\m = \frac{-8}{240} \times \frac{15}{-1}\\\\ m = \frac{120}{240}\\\\m = \frac{1}{2}

\text{Substitute } m = \frac{1}{2} \text{ and } (x_1, y_1) = (\frac{2}{5} , \frac{19}{20}) \text{ in eqn 1 }

y - \frac{19}{20} = \frac{1}{2}(x - \frac{2}{5})\\\\y - \frac{19}{20} = \frac{x}{2} - \frac{1}{5}\\\\\frac{x}{2} - y = - \frac{19}{20} + \frac{1}{5}\\\\\frac{x}{2} - y = \frac{-15}{20}\\\\Simplify\\\\y = \frac{1}{2}x + \frac{3}{4}

In standard form,

y = \frac{4x+6}{8}\\\\8y = 4x + 6\\\\4x - 8y = -6

Thus the equation of line is found
