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

Hello there,

(05.03 LC)

Determine the solution to f(x) = g(x) using the following system of equations:

f(x) = 3x − 23

g(x) = −4.5x + 7

Answer: x = 4

Hello,

$\dfrac{d^2( \int\limits^x_0 { \dfrac{2}{t^2+3t+1} } \, dt )}{dx^2} = \dfrac{d(\dfrac{2}{x^2+3x+1}) }{dx} \\

= \dfrac{-2(2x+3)}{(x^2+3x+1)^2}$

Four ninths plus nine eighteenths :]

Answer: 17/18

In words, this is seventeen eighteenths

==========================================

Work Shown:

4/9 + 9/18

8/18 + 9/18 ... see note below

(8+9)/18

17/18

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

note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.

The diagram below shows a visual representation of why 4/9 = 8/18.

In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.
