Given 5n² + 6n + 7 = n² - 4n : a. Find the value of the discriminant. b. State the number and type of roots/solutions/zeros.[2 r

Vika [28.1K]

$\bf 5n^2+6n+7=n^2-4n\implies 5n^2+6n+7-n^2+4n=0
\\\\\\
4n^2+10n+7=0\\\\
-------------------------------\\\\
\begin{array}{llccll}
&{{ 4}}x^2&{{ +10}}x&{{ +7}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}$

if you get a positive value, that means 2 real solutions
if you get 0, means 1 real solution only
if you get a negative value, is an imaginary root solution, same as saying no solution.

A person filing her federal income tax return with the Single filing status had a taxable income of $79,950. According to the ta

Tom [10]

Answer:

The income that she will have left over after paying his

federal income tax = $63,775.

Step-by-step explanation:

The amount of taxable income = $79,950

So, the taxable income will be in the range from $33,950 to $82,250.

It means, there will be $4675 fixed tax and additional 25% tax on the amount over $33,950.

As

The amount over $33,950 = $79,950 - $33,950 = $46,000

So

The additional tax = 46000 × 0.25 = $11,500 ∵25% = 0.25

So, the total federal income tax will be: $11500 + $4675 = $16,175

Therefore, the income that she will have left over after paying his federal income tax = $79,950 - $16,175 = $63,775.
