For which values of x is the expression undefined? x2 – 49 x2 – 16

Lyrx [107]

You meant to say x^2 - 49 and the second binomial is x^2 - 16.

x^2 - 49 = (x - 7) (x + 7).

Set each factor to 0 and solve for x individually.

x - 7 = 0

x = 7

x + 7 = 0

x = -7

Do the same for x^2 - 16.

Here is the set up:

x^2 - 16 = (x - 4) (x + 4).

Take it from here.

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of

Liula [17]

Okay, here we have this:

Considering the provided information and grades, we are going to calculate the requested GPA, so we obtain the following:

Then we will substitute in the following formula:

$GPA=\frac{Grades\ast Credits}{Total\text{ credits}}$

Then:

$\begin{gathered} GPA=\frac{3.8\cdot5+1.9\cdot2+3.0\cdot5+2.8\cdot4}{16} \\ GPA=\frac{19+3.8+15+11.2}{16} \\ GPA=\frac{49}{16} \\ GPA=3.06 \end{gathered}$

Finally we obtain that the student's GPA for that term is approximately 3.06.
