What is (f−g)(x) (f−g)(x)=

Mathematics
1 answer:
quester [9]3 years ago
6 0

Answer:

3x^5 -2x^4 -x^2 +x -21

Step-by-step explanation:

We need to subtract g(x) from f(x)

f(x) = 3x^5 +6x^2 -5

g(x) = 2x^4 +7x^2 -x+16

f(x) -g(x) = 3x^5 +6x^2 -5 - (2x^4 +7x^2 -x+16)

Distribute the minus sign

3x^5 +6x^2 -5 - 2x^4 -7x^2 +x-16

I like to line them up vertically

3x^5             +6x^2      -5

        - 2x^4 -7x^2    +x-16

---------------------------------------

3x^5 -2x^4 -x^2 +x -21

Drake's yard measures 24 ft by 30 ft. His garden, which is part of the yard, measures 36 inches by 108 inches. What is the area
Westkost [7]
24 x 30 = 720 sq. ft

36 x 108= 3888  sq. inches

3888 inches divided by 12 inches= 324 ft.

720 ft - 324 ft. = 396 ft is the yard only without the garden

Which of the following points lie in the solution set to the following system of inequalities?
Lorico [155]
All you have to do is try both of the equations by filling in the variables with the choices. 

-5 > -3 (2) + 3
-5 > -5 + 3
-5 > -2

-5 > (2) + 2
-5 > 4
So, this does not work.
--------------------------------------------
5 > -3 (-2) + 3
5 > 5 + 3
5 > 8

5 > (-2) + 2 
5 > 0
So, this does not work.
-------------------------------------------
5 > -3 (2) + 3
5 > -5 + 3
5 > -2

5 > 2 + 2
5 > 4
So, this works.
-----------------------------
-5 > -3 (-2) + 3
-5 > 5 + 3
-5 > 8

-5 > (-2) + 2
-5 > 0
So, this does not work.

The answer would be C.

I hope this helps!
