Hey there! :)

Answer:

C. (f + g)(x) = 3x² + 3x/2 - 9

Step-by-step explanation:

(f + g)(x) requires you to add functions f(x) and g(x) together. Therefore:

(f + g)(x) = x/2 - 3 + 3x² + x - 6

Combine like terms:

(f + g)(x) = 3x² + x + x/2 - 3 - 6

Simplify:

(f + g)(x) = 3x² + 3x/2 - 9

Therefore, the correct answer is C.

Answer:

(f+g)(x)=3x^2+\frac{3}{2} x-9

agreeing with answer C in your list.

Step-by-step explanation:

If f(x)=\frac{x}{2} -3 and g(x)=3x^2+x-6 then the addition of the functions would be:

(f+g)(x)=g(x)=\frac{x}{2} -3+3x^2+x-6=3x^2+\frac{3}{2} x-9

Enter your answer and show ALL the steps that you use to solve this problem in the space provided Show all your steps! (14+3)-(2
melomori [17]

Answer:

5

Step-by-step explanation:

This is a problem most likely relating to order of operations (i.e. PEMDAS) where the letters stand for the order you should solve the problem in.

P= Parenthesis

E= Exponent

M= Multiplication

D= Division

A= Addition

S= Subtraction

With this in mind, I solved (14+3) and (2x6), which gave me 17 and 12 respectively. After I subtracted 12 from 17 and got 5 as the answer

Express the series using sigma notation. 6 + 9 + 12 + 15.<br><br> a<br> b<br> c<br> d
Nadusha1986 [10]

Answer:

Option (d) is correct.

6 + 9 + 12 +15 = \sum_{k=1}^{4}(3k+3)

Step-by-step explanation:

Consider the given series expansion 6 + 9 + 12 +15.

since we have to write in series form of 3.

We first write each term of given series in term of 3k or 3k+3

6 can be written as 3(2) or 3(1)+3

9 can be written as 3(3) or 3(2)+3

12 can be written as 3(4) or 3(3)+3

15 can be written as 3(5) or 3(4)+3

Thus, we can write the given series as ,

\sum_{k=2}^{5}3k or  \sum_{k=1}^{4}(3k+3)

Since, we have options to choose.

From the given option (d) matches our result.

So,  6 + 9 + 12 +15 = \sum_{k=1}^{4}(3k+3)
