That's a lot of points for this question. You don't have to offer that much.
Leading Coefficient: When written in standard form (starting with the variable with the highest power, going to the variable with the next highest power ... all the way down to a number with no variable), the leading coefficient is the number in front of the variable with the highest power.
Let me put this less technically. Find the variable with the highest power. The number in front of that variable is the leading coefficient.
Write this in standard form. 5x^4 -2x + 1
The number in front of the x^4 is the answer.

Answer:
B. f(x) = 3/(x^2 +2x +1)
E. f(x) = 5/(3+x)
Step-by-step explanation:
The above functions have denominators that are zero at one point. For B, that point is x=-1; for E, that point is x=-3. When the denominator is zero, the function is undefined, so the corresponding x-value must be excluded from the domain.

As written, choice D also qualifies. This is because the function written in the answer list here is ...
It will be undefined for x=0.

<em>Comment on writing rational functions</em>
When the division symbol (/ or ÷) is used with a denominator that is a product or sum, that product or sum must be enclosed in parentheses. When the expression is typeset, the division bar acts as a grouping symbol. When the expression is written in text, a grouping symbol, such as parentheses, must be added.
That's all you need to do
Answer:
7/9 or ~77.7778% or 0.777778
Step-by-step explanation:
First you need to find the total amount or marbles.
Next, find the sum of <em>just</em><em> </em>the<em> </em>blue<em> </em>and red marbles.
Now, find the probability by dividing or simplifying the number of blue and red by the total.
- 14/18= <u>7/9</u> OR <u>~</u><u>0</u><u>.</u><u>7</u><u>7</u><u>7</u><u>7</u><u>7</u><u>8</u>
Using a z-score table:
P(z<1.87)=0.96926
P(z<1.87)=0.96926 x 100%
P(z<1.87)=96.926%
