Find the inverse 2x+6/5

Mathematics
1 answer:
Inessa [10]3 years ago
3 0

ANSWER

\frac{5x - 6}{2}

EXPLANATION

The given function is

\frac{2x + 6}{5}

Let

y =  \frac{2x + 6}{5}

Interchange x and y.

x=  \frac{2y + 6}{5}

Solve for y.

5x=2y+6

5x-6=2y

Divide both sides by 2

\frac{5x - 6}{2}  = y

Hence the given function has inverse

\frac{5x - 6}{2}

Answer:  y = -x/3 + 5

Step-by-step explanation:

What we know:

- Our points are (-3, 6) and (0, 5)

First, we need to find the slope. The formula for finding slope is y2 - y1/x2 - x1.

Now, we need to plug in our values.

5 - 6/0 - (-3)

Solve.

-1/3

Our slope is -1/3.

But now we need to find the y-intercept. To do this, we will use the equation y = mx + b.

You can use either coordinate pair, but I will be using (-3, 6) first.

Plug in the values.

6 = -1/3(-3) + b

Simplify.

6 = 1 + b

Subtract 1 to both sides.

6 - 1 = 1 - 1 + b

5 = b

The y-intercept is 5. Now we can put everything together!

y = -1/3x + 5

y = -x/3 + 5

For the coordinate (0, 5), you do the same thing.

5 = -1/3(0) + b

5 = 0 + b

5 = b

y = -1/3x + 5

y = -x/3 + 5

Some steps in solving an equation are more efficient than others. Complete parts (a) though (d) to determine the most efficient
Vinil7 [7]

Answer:

The solution of the given equation   x =11

Step-by-step explanation:

Given equation 34 - 5x = -21

<u>Step :-(a)</u>

               Given equation 34 - 5x = -21

                              Subtracting '34' on both sides , we get

                                         34 - 5x -34 = -21 -34

<u>Step:-(b)</u>

                             on simplification , we get

                                          -5x = -55

<u>Step:-(c)   </u>

                           Dividing ' -5' on both sides , we get

                                             \frac{-5x}{-5} =\frac{-55}{-5}

                        Cancellation '-5' on both sides , we get

                                               x = 11

<u>Step :-(d)</u>

                   The solution of the given equation   x =11
