Hey there! I'm happy to help!

To find (f-g)(x), we simply subtract the function g from the function f.

6x²-2x-5-(-2x²+3x-1)

We combine like terms.

6x²+2x²=8x²

-2x-3x=-5x

-5-(-1)=-5+1=-4

Therefore, (f-g)(x)=8x²-5x-4

Have a wonderful day! :D

Answer: (f-g)(x)=8x²-5x-4

Step-by-step explanation:

(f-g)(x) means to subtract f(x) and g(x). Since we are given f(x) and g(x), we can directly subtract them.

(f-g)(x)=6x²-2x-5-(-2x²+3x-1) [distribute -1]

(f-g)(x)=6x²-2x-5+2x²-3x+1 [combine like terms]

(f-g)(x)=8x²-5x-4

Now, (f-g)(x)=8x²-5x-4 is our answer.

Answer:

Each guest would get 6 party favors.

Step-by-step explanation:

First, we find out how many party favors Amy bought. 3 bags of 12 party favors equals 36 party favors (3x12)

So, divide 36 party favors by 6 guests, and you get the final answer of 6 party favors per guest.

Hope this helps!!

the diameter of your bicycle wheel is 34 inches.What is its radius?How far will you move in one turn if your wheel?What is the d

gulaghasi [49]

Answer:

Step-by-step explanation:

The radius of a circle is always half the radius.

Thus, in this case, the radius is (1/2)(34 in) = 17 in.

The "how far" question is answerable by finding the circumference of the wheel. The circumference, C, is found by calculating C = πd, where d is the diameter of the circle in question.

Here, C = (34 in)π, which comes out to 106.81 inches. The bike will move 106.81 inches forward if the wheel turns once.

If the wheel turns 5 times, the total distance traveled is 5 times the circumference, or 5(106.81 in) = 534.07 in.
