f(x) = 3x +2

f(2) = 3(2) + 2 = 8

Now

f(x) = (2x -7) / 3

let f(x) = y and f(y) = x;

y = (2x -7) / 3

x = (3y + 7) / 2

So

f(y) = (3y + 7) / 2

this f(y) is the inverse of f(x); hence

f^-1 (x) = (3x + 7) / 2

Now f^-1(3) = (9+7) / 2 = 8

For the third and last part,

2y + 14 = 4y – 2

2y = 16

y = 8

<span>Hence all the three parts gives the same results.</span>

Equation:
jekas [21]

Answer:

x = 41; B = 41°; A = 77°

Step-by-step explanation:

All of the angles add up to 180 so to solve for X you do (x) + (2x-5) + (62) = 180. Solve for X and you get 41. Lastly plut the answer back into the equation.

Enter the value of p so the expression 5/6-1/3nis equivalent to p(5-2n).
SIZIF [17.4K]
Take LCD of 6 and 3 = 6 is the lcm
5/6 -2/6n 
(5-2n)/6.

Now, what number can be multiplied to the right side of the equal sign to get the value of P

The answer is 1/6 as the left side is divided by 6, so multiply the right side by 1/6 to make it equivalent.

The vector 〈4,1〉 describes the translation of A(-1, w) to A'(2x+1,\ 4) and B(8y-1,1) onto B'(3,3z) . Find the values of w, x, y,
expeople1 [14]

The values of the variables associated ot translation operations are (w, x, y, z) = (3, 1, 0, 2 / 3).

<h3>How to determine the values of the variables associated to translation operations</h3>

Herein we find two translation cases of points set on Cartesian plane. Translations are rigid operations of the form:

P'(x, y) = P(x, y) + T(x, y)

Where:

  • P(x, y) - Original point
  • P'(x, y) - Resulting point
  • T(x, y) - Translation vector

Now we proceed to determine the values of the variables w, x, y, z behind each translation operation, substitute on each component and solve the resulting formula:

T(x, y) = A'(x, y) - A(x, y)

(2 · x + 1, 4) - (- 1, w) = (4, 1)

(2 · x + 2, 4 - w) = (4, 1)

(x, w) = (1, 3)

T(x, y) = B'(x, y) - B(x, y)

(3, 3 · z) - (8 · y - 1, 1) = (4, 1)

(4 - 8 · y, 3 · z - 1) = (4, 1)

(y, z) = (0, 2 / 3)

In a class of strength 60, 75% like to become teachers. how manu dont like to be teachers?
timurjin [86]

No. of people don't like to be teacher

= 100% - 75% = 25%

<h3>\frac{25}{100}  \times 60 \\  = 15</h3>

So, 15 number of students doesn't like to be teacher
