What is the inverse of f(x)=−3x+5?
kotykmax [81]

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

Bridget takes a 5-inch by 4-inch rectangle of fabric and cuts from one corner of the piece of fabric to the diagonally opposite
mario62 [17]

Answer:

Perimeter of each triangles are equivalent to 15.4 inches.

Step-by-step explanation:

Given:

A rectangle :

Length of the rectangle = 5 inches

Width of the rectangle =4 inches

As Bridget cuts it from one corner to the other corner,its forms two right angled triangle.

The diagonal will be treated as the hypotenuse.

Lets say that the length of the hypotenuse is 'x'.

Using Pythagoras formula:

⇒ (hypotenuse) = \sqrt{(perpendicular)^2+(base)^2}

Plugging the values:

⇒ hypotenuse = \sqrt{5^2+4^2}

⇒ hypotenuse = \sqrt{25+16}

⇒ hypotenuse =\sqrt{41}

⇒ hypotenuse = 6.40  inches

Now we have to find the perimeter :

Perimeter = Summation of length of all sides.

So,

Perimeter  of each triangle = (length + width + hypotenuse)

⇒ Perimeter =(5+4+6.4)

⇒ Perimeter =15.4  inches

Perimeter of each triangle, as they are equally sized are same that is   15.4 inches.
