Ok so (4x-12) first yu want to get x by itself to get the answer so divide by 4 in both side so you could cancel out the 4. And then you would have to do 12 divided by 4 which is 3 so x=3
Hope this helped.

you can work 8 hours today. based on the information below about your current work, rank order the activities you will complete
Montano1993 [528]

The rank order of the activities to be completed are:

  1. Work on ongoing project
  2. Investigate customer issue
  3. Complete Online Training
  4. Attend team meeting
<h3>How to order the events?</h3>

From the complete question (see attachment) the events must be ordered based on their priorities, followed by the time and then impact.

Using the above highlight, the events with the top priorities are:

Events 1 and 2

The events with the most number of hours are:

Events 1 and 2

Event 4 has more priority than event 3.

So, we have the following order

1, 2, 4 and 3

If limx→3f(x)=7, which of the following must be true? I. f is continuous at x = 3 II. f is differentiable at x = 3
Viktor [21]

Without knowing anything else about f(x), neither of these need be true.

Suppose

f(x)=|x-3|+7=\begin{cases}10-x&\text{for }x3\\0&\text{for }x=3\end{cases}

Then (I) isn't true because, while the limit exists as x\to3 and is equal to 7, we have f(3)=0\neq7, so f(x) is not continuous there.

(II) also true because f(x) is not differentiable at x=3; that is,

\displaystyle\lim_{x\to3^-}f'(x)=\lim_{x\to3}(10-x)'=\lim_{x\to3}(-1)=-1

but

\displaystyle\lim_{x\to3^+}f'(x)=\lim_{x\to3}(x+4)'=\lim_{x\to3}1=1

which means the derivative does not exist at x=3.

What is the quadratic function f(x)=x^2+2x-2 in vertex form?
NemiM [27]
Given: f(x) = x² + 2x - 2
Add 2 to both sides: f(x) + 2 = x² + 2x
Complete the square: f(x) + 2 + (1) = x² + 2x + (1) → f(x) + 3 = (x + 1)²
Subtract 3 from both sides: f(x) = (x + 1)² - 3

Answer: B

a circular mirror is surrounded by a square metal frame. the radius of the mirror is 5x. the side length of the metal frame is 1
Eva8 [605]
Since the side of the square frame is 15x, the area of the frame in whole would be:

(15x)² = 225x²

Now if we subtract out the circle mirror with a radius of 5x, we get:

225x² - πr²
225x² - π(5x)²
225x² - π25x²

We can factor out a 25x² and get:

25x² (9 - π)
