If f(x) = 8 -3 and g(x) = 3x2 + x-6, find (f + g)(x).
Marizza181 [45]

Answer:

D

Step-by-step explanation:

(f+g)(x)   basically means to "ADD" f(x) and g(x).

We have

f(x)=\frac{x}{2}-3

and

g(x)=3x^2+x-6

Now we simply add these two, adding like terms as shown below (and simplify):

(f+g)(x)=f(x)+g(x)\\=(\frac{x}{2}-3)+(3x^2+x-6)\\=3x^2+\frac{1}{2}x+x-3-6\\=3x^2+\frac{3}{2}x-9

Correct answer is D

What is a good way to ace a level 5-7 maths test? I need some good tactics...subjects in particular.
zavuch27 [327]
It's important to study and study. I recommend studying the homework or study sheet the day before the test. Most likely the teacher has added a similar problem on to the test. Add a friend to help you study. To make it fun, buy candy and quiz yourself or friends! If you get a problem right, them give yourself candy.

when two fractions refer to the same whole, explain why the fraction with a lesser denominator has larger pieces than the fracti
olya-2409 [2.1K]

Answer with explanation:

Consider a Rectangular room, in which four people are residing and another congruent room,in which six people are dwelling.

If Area Occupied by two rooms are same

Then, Area occupied by each person in first room,if there are four person in first room, if represented in terms of fraction is equal to one fourth\frac{1}{4}=0.25 m^2.

And, Area occupied by each person in second room,if there are six person in second room, if represented in terms of fraction is equal to one sixth\frac{1}{6}=0.17 m^2.

So,→→ Area occupied by each person in which four people are residing>Area occupied by each person in which six people are residing.

→→So,Fraction with a lesser denominator has larger pieces(Larger area) than the fraction with a greater denominator smaller pieces(smaller area).
