What is the inverse of the function g ( x ) = − 3 ( x + 6 ) g(x)=−3(x+6)g, left parenthesis, x, right parenthesis, equals, minus
aleksley [76]

Answer:

Then inverse of the given equation is given by ,f^-1(x)=  (-x/3 - 6)

Step-by-step explanation:

Given:

Function as g(x)=-3(x+6).

To Find :

The inverse function of the g(x).

Solution:

We know that step involving to convert into inverse function as follows :

Further ,

  1. Replace g(x) with function as  "y",

             hence it becomes ,

            y=-3(x+6)

     2.Then solve for the x value ,

        it becomes as ,

      \frac{-y}{3}=x+6,

    \frac{-y}{3}-6=x

     3. Replace x with y and y with x we get ,

   \frac{-x}{3}-6=y.

it is written as ,

y=f^-1(x)=  -x/3-6

Then inverse of the given equation is given by ,f^-1(x)=  -x/3-6.

If R is the midpoint of QS, QR = 8x – 51 and RS = 3x – 6, find QS.
dusya [7]

Answer:

42 units

Step-by-step explanation:

If R is the midpoint of QS, then by definition, QR = RS. Since QR = 8x - 51 and RS = 3x - 6, set these equal to solve for x:

QR = RS

8x - 51 = 3x - 6

5x = 45

x = 9

Now that we know x = 9, we can plug this back into one of the expressions for QR or RS to find its length:

QR = 8x - 51 = 8 * 9 - 51 = 72 - 51 = 21

Since half of QS is 21, then the whole of QS is twice that:

2 * 21 = 42

The answer is thus 42 units.

In the first table, y = 4x. So y is proportional to x.

In the second table, y is not proportional to x.

In the third table, 2y = 3x. So, y is proportional to x.
