6x+9/x-5 x is not equal to 5 find inverse
algol [13]
You have f(x)=(<span>6x+9)/(x-5) and want to find the inverse function?  Please note that the parentheses are obligatory here.

1.  Replace "f(x)" with y:   y = </span>(6x+9)/(x-5)
<span>
2.  Interchange the variables x and y:     x</span> = (6y+9)/(y-5)

3.  Solve this result for y:     x(y-5) = (6y+9), or xy-5x = 6y+9.  Then:
                                                             
                                            xy-6y = 9 + 5x, or y(x-6) = 9+5x
                                                             9+5x
                     Then                      y = --------------                       
                                                             x-6

Here x may not = 6, because division by zero would occur otherwise.

Find the volume of a sphere with radius of 10 feet. round to the nearest whole number.
Alexxandr [17]
Volume = (4/3) * PI * r^3
Volume = (4/3) * 3.14159 * 10^3
Volume = (4/3) * 3.14159 * 1,000
Volume = 4,188.786666666666
Volume = 4,189 cubic feet

Suppose that x=6 and y=8. If y is inversely related to x, what is y when x=3?
andrey2020 [161]
\bf \qquad \qquad \textit{inverse proportional variation}\\\\&#10;\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby &#10;\begin{array}{llll}&#10;k=constant\ of\\&#10;\qquad  variation&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;\textit{we also know that }&#10;\begin{cases}&#10;x=6\\&#10;y=8&#10;\end{cases}\implies 8=\cfrac{k}{6}\implies 48=k&#10;\\\\\\&#10;therefore\qquad \boxed{y=\cfrac{48}{x}}&#10;\\\\\\&#10;\textit{when x = 3, what is \underline{y}?}\qquad y=\cfrac{48}{3}

What number is missing? explanation please
-BARSIC- [3]
The missing number is 12

because the pattern is that the the numbers below and to the right of a number equals that number. ex: 3+4=7. so in order to find the missing number you have to do the opposite of addition, which is subtraction. (17-5=12)
