f(x)=3x-23,\ g(x)=-4.5x+7\\\\f(x)=g(x)\iff3x-23=-4.5x+7\qquad\text{add 23 to both sides}\\\\3x=-4.5x+30\qquad\text{add 4.5x to both sides}\\\\7.5x=30\qquad\text{divide both sides by 7.5}\\\\\boxed{x=4}

F(x)=4x-3<br> G(x)=x^3+2x<br> Find (f-g)(x)
dexar [7]
You gotta remember that (f-g)(x) means f(x) - g(x).

So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3

One week a computer store sold a total of 36 computers and external hard drives. the revenue from these sales was ​$30875 . if c
melamori03 [73]

To solve this problem you must apply the proccedure shown below:

1. You must make a system of equation by using the information given in the problem above. Then, let's call:

x: The number of computers sold.

y: The number of hard drives sold.

2. Therefore, you have the following system of equations:

\left \{ {{x+y=36} \atop {1180x+125y=30875}} \right.

2. Solve for x in the first equation and substitute it into the second equation:

x=36-y\\ 1180(36-y)+125y=30875

3. Solve for y:

42480-1180y+125y=30875\\ y=11

4. Substitute the value of y into the first equation to calculate x:

x+11=36\\ x=25

Therefore, the answer is: The store sold 25 computers and 11 hard drives.
