How many numbers are reciprocal of themselves?

Mathematics
1 answer:
const2013 [10]3 years ago
6 0

Answer:

  two: +1 and -1

Step-by-step explanation:

If a number is equal to its own reciprocal, it will satisfy the equation ...

  x = 1/x

Multiplying by x and subtracting 1 gives ...

  x^2 -1 = 0

This factors as ...

  (x -1)(x +1) = 0

By the zero product rule, the solutions are those values of x that make one or more factors zero:

  x = 1

  x = -1

There are two self-reciprocals.

If f(x)...............
alex41 [277]

Answer:

The inverse is 5x-6

Step-by-step explanation:

To find the inverse of a function

y = ( x+6) /5

Exchange x and y

x = ( y+6)/5

Solve for y

Multiply each side by 5

5x = (y+6)/5 *5

5x = y+6

Subtract 6  from each side

5x-6 = y+6-6

5x-6 =y

The inverse is 5x-6

The Potter Valley basketball team did not record how many baskets each player made during the last game. Jenny remembers that sh
lesya692 [45]

Answer:  The approximate values that every player make are,

Tammy = grace = 5.43 baskets

Jenny = 16.30 Baskets

Alex = 11.43 Baskets

Joan = 1.43

Step-by-step explanation:

Let Grace made x baskets.

Then According to the question,

Jenny made baskets = 3x

Alexis made basket = x + 6

Joan made basket = x - 4

Tammy made baskets = x

Since,  Altogether the five players made 40 baskets.

⇒ x+ 3x + x + 6 + x - 4 + x = 40

⇒ 7x + 2 = 40

⇒ 7x = 38

⇒ x = 38 / 7 = 5.42857142857 ≈ 5.43

Thus, Grace made baskets= Tammy made baskets = x = 5.43

Jenny made baskets = 3 × x = 16.2857142857 ≈ 16.30

Alexis made basket = x + 6 = 11.4285714286  ≈ 11.43

Joan made basket = x - 4 = 1.42857142857

≈ 1.43
