Let y=f(x)=(3x+7)/(x-2) find a rule for f^-1

Murrr4er [49]

Answer:

$f^{-1}(x)=\frac{2x+7}{x-3}$ .

Step-by-step explanation:

The given function is $f(x)=\frac{3x+7}{x-2},\:x\ne2$ .

We want to find a rule for $f^{-1}(x)$ .

Let $y=\frac{3x+7}{x-2}$ .

Interchange x and y.

$x=\frac{3y+7}{y-2}$ .

Solve for y.

$x(y-2)=3y+7$ .

Expand

$xy-2x=3y+7$ .

Group y-terms

$xy-3y=7+2x$ .

Factor

$(x-3)y=7+2x$ .

$y=\frac{2x+7}{x-3}$ .

$\therefore f^{-1}(x)=\frac{2x+7}{x-3},\:x\ne3$ .

Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

3x - 10 + 6x + 5 + 4x - 10 = 180, simplify left side

13x - 15 = 180 ( add 15 to both sides )

13x = 195 ( divide both sides by 13 )

x = 15
