Brandon found that a solution of x = 1 was extraneous for his function. What would be a possible denominator in Brandon's function?2x + 4

x2 + 3x + 9

3x - 11

x2 + 3x - 4

Answers

An extraneous solution is obtained when the simplified version of the function drives to a value thas does not belong to the domain of the complete function.

So, if x = 1 is an extraneous solution, it does not belong to the original domain.

if when you replace x = 1 in the expression of the denominator it results in 0, then it is an extraneous solution, because you cannot accept it as a valid solution.

Then we must check which of the expressions listed in the options drive to that possibility.

The promising choice is x^2 + 3x - 4.

Inded,  If you substitute x = 1, you get (1)2 + 3(1) - 4 = 1 + 3 - 4 = 4 - 4 = 0.

And the answer is x^2 + 3x - 4.

Answer:

x^2+3x-4

What is the relationship between gross pay and net pay?

Answers

Your gross pay and net pay both have to do with taxes and the amount of money you earn, but they differ from one another:

Gross pay: This is the total amount of money you earned during the pay period, your salary multiplied by the number of hours you worked. 

Net pay: This number will be less than the gross pay because this is how much you actually take home after taxes are taken out of your check.

Which one of the following is a true statement about a circle inscribed in a regular polygon? A. The area of the circle is equal to the area of the polygon.
B. The sides of the polygon are chords of the circle.
C. The vertices of the polygon are on the circumference of the circle.
D. The sides of the polygon are tangents of the circle.

Answers

Given that a circle is inscribed in a regular polygon, it is true that the sides of the polygons are tangents of the circle. The area of the circle is always less than the area of the polygon. When the polygon is inscribed in the circle, then the sides of the polygon are chords of the circle and the vertices of the polygon are on the circumference of the circle. Answer is D.
