Answer:

x= -2 and 9

Step-by-step explanation:

x ^{2}  + 7x - 18

factorize it

- 18 = 2×3×3

TO MAKE IT 7

3×3=9

9-2 =7

x ^{2}  + 9x - 2x - 18x = 0

x(x+9)-2(x+9)=0

x-2=0 ,x+9=0

x =2 x=-9

Vertical angles are equal, so
.. 3x +8 = 5x -20
.. 28 = 2x . . . . . . . . add 20-3x
.. 14 = x . . . . . . . . . . divide by 2

Each of the vertical angles is 3*14 +8 = 50°, so the supplementary one is 130°.
.. 5*14 +4y = 130
.. 4y = 60 . . . . . . . . subtract 70
.. y = 15 . . . . . . . . . . divide by 4

The values of interest are
.. x = 14
.. y = 15

Given f(x)= 3x+2, what is the Inverse Function?
Grace [21]

Answer:

Step-by-step explanation:

For this case we must determine the inverse of the following function:

f(x)=3x-2

Step 1:

We would write

y=f(x) or y=3x-2

Step 2:

We clear x:

y+2=3x

\frac{y+2}{3}=x

Step 3:

"x" and "y" are exchanged:

y=\frac{x+2}{3}

The inverse is:

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