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: B

Step-by-step explanation:

The area of the entire rectangle is (10+30)(15+10) = 1000, and the area of region II is (30)(15)=450. Hence, the desired probability is 450/1000 = 45%.

Find the value of 2.<br> 78°<br> 1200<br> 15°<br> B

andrew11 [14]

I tried but see if this helps you In algebra, it is easy to find the third value when two values are given. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.

Justify each step in solving the equation -3(2x-3)=25-8x by writing a reason for each statement.

Mice21 [21]

Answer: x= 8.

Step-by-step explanation: Given equation -3(2x-3)=25-8x.

Step 1: We have -3 in front of (2x-3). We always simplify a parenthesis first.

Therefore, applying Distributive property in first step, we get

-6x +9 = 25-8x.

Step 2: We need to get rid 9 from left side to get constant numbers on right side.

9 is being added on left side.

So, we would apply reverse operation of addition.

Therefore, applying Subtraction property of equality, we get

-6x +9-9 = 25-8x-9

-6x =16 -8x.

Step 3: We need to get rid 8x from right side.

The reverse operation of subtraction is addition.

Therefore, applying Addition property of equality, we get

-6x+8x =16 -8x+8x

2x = 16.

Step 4: We need to isolate it for x.

So, applying Division property of equality, we get

$\frac{2x}{2}=\frac{16}{2}$
