Answer:

f-¹(x) = (4- x)/ 3

Step-by-step explanation:

inverse of a function is nothing but the value of x in terms of f(x)

like

if we write f(x) as y we'd get

y = - 3x + 5

so, ill express x in terms of y:-

y= -3x + 4

  • adding 3x on both sides of the equation

y + 3x = -3x + 3x + 4

  • subtracting y on both sides

y - y + 3x = 4 - y

3x = 4 - y

  • dividing the whole equation by 3

x = (4 - y)/ 3

soo, the inverse of the function is x = (4- y)/ 3

mostly we write the inverse in terms of x, hey! don't get confused, when i say this, I simply mean that we're gonna replace y with x and x with f-¹(x).

therefore,

f-¹(x) = (4- x)/ 3

Answer:

f^{-1} (x) = \frac{-x}{3} + \frac{5}{3}

Step-by-step explanation

y = -3x +5 ---> x = -3y + 5 -> y = \frac{x - 5}{-3}

If the legs of a right triangle are x, (2x - 1) and its hypotenuse is (2x + 1), what is the value of x?​
Ber [7]

Answer:

x=8

Step-by-step explanation:

(2x + 1)² = x² + (2x - 1)² = x² + (2x - 1)(2x - 1)

(2x + 1)(2x + 1) = x² + 4x²-2x-2x+1

4x²+2x+2x+1 = 5x²-4x+1

4x²+4x+1 = 5x²-4x+1

0= 5x²-4x²-4x-4x+1-1

0= x²-8x

x²-8x=0

x²=8x

x=8

The ancient Greeks could bisect an angle using only a compass and straightedge.A. TrueB. False
Gala2k [10]

Answer: True.

The ancient Greeks could bisect an angle using only a compass and straightedge.

Step-by-step explanation:

The ancient Greek mathematician <em>Euclid</em> who is known as inventor of geometry.

The Greeks could not do arithmetic. They had only whole numbers. They do not have zero and negative numbers.

Thus, Euclid and the another Greeks had the problem of finding the position of an angle bisector.

This lead to the constructions using compass and straightedge. Therefore, the straightedge has no markings. It is definitely not a graduated-rule.

As a substitute for using arithmetic, Euclid and the Greeks learnt to solve the problems graphically by drawing shapes .
