B is the answer to this question.
AleksandrR [38]3 years ago
4 0

Answer:

B) -\frac{a}{-b}

Step-by-step explanation:

The value -\frac{-a}{b} is the same as \frac{a}{b} since the negatives cancel out to make a positive.

Option A is incorrect since the overall value of the term would be negative. Option B however is correct since there will not be a negative value in the denominator of a fraction and thus it cancels out with the negative in front of the fraction to produce the value of \frac{a}{b} which is the same as the expression given in the question, thus it is option B.

Write the sum using summation notation, assuming the suggested pattern continues. -9 - 3 + 3 + 9 + ... + 81
noname [10]

Answer:

Option A:        $ \sum_{n = 1}^{15} {\textbf{- 9 + 6 n}} $

Step-by-step explanation:

We are given with the series - 9  - 3  + 3   +  9 +  . . . .  +  81.

Note that the second term is obtained by adding 6 to the first term.

Each consecutive term is obtained by adding 6 to its previous term.

Therefore, we should be adding six two times to get the third term from the first term.

Putting it Mathematically, we get: - 9 + 6n

This gives all the terms of the sequence. Since, we have to add all the terms we take the summation.

Also, note that 81 is the 15 th term.

Therefore, - 9  - 3  + 3   +  9 +  . . . .  +  81 =    $ \sum_{n = 1}^{15} {- 9 + 6 n} $

Hence, the answer.

Graph y=-1/4x+5 how do you graph this?
GrogVix [38]

It is a linear function. The graph is a straight line.

We need only two points to plot a graph of a linear function.

Select two any x values and calculate the y values:

y=-\dfrac{1}{4}x+5\\\\for\ x=0\to y=-\dfrac{1}{4}(0)+5=0+5=5\to(0,\ 5)\\\\for\ x=4\to y=-\dfrac{1}{4}(4)+5=-1+5=4\to(4,\ 4)

Evaluate the expression 263 + 5 when b = 3.<br> 263 +5 = 2(3): +5<br> =
ExtremeBDS [4]

Given:

The expression is:

2b^3+5

To find:

The value of the given expression when b=3.

Solution:

We have,

2b^3+5

Substituting b=3 in the above expression, we get

2b^3+5=2(3)^3+5

2b^3+5=2(27)+5

2b^3+5=54+5

2b^3+5=59

Therefore, the value of given expression at b=3 is 59.
