Answer:

a*a^{-1}=a*\frac{1}{a}= \frac{a}{a}=1 \\\\a\in R

Step-by-step explanation:

We are talking about the multiplicative inverse of any number. The multiplicative inverse of a number is another number that multiplied by the first, results in the neutral element of the product, that is, the unit. If we have a real number a, then its multiplicative inverse is denoted by a^{-1}, and it is true that:

a*a^{-1}=a*\frac{1}{a}= \frac{a}{a}=1 \\\\a\in R

It's important to note that the multiplicative inverse exists in rational numbers, in real numbers, and in complex numbers.

A computer online service charges one hourly rate for regular use but a higher hourly rate for designated "premium" areas. One c
N76 [4]

Answer: the service charge per hour for premium services is $5.5

the service charge per hour for regular services is $3

Step-by-step explanation:

Let x represent the service charge per hour for premium services.

Let y represent the service charge per hour for regular services.

One customer was charged $38 after spending 2 h in premium areas and 9 regular hours. It means that

2x + 9y = 38- - - - - - - - - - - 1

Another customer spent 3 h in premium areas and 6 regular hours and was charged $34.50. It means that

3x + 6y = 34.5- - - - - - - - - - -2

We would eliminate x by multiplying equation 1 by 3 and equation 2 by 2. It becomes

6x + 27y = 114

6x + 12y = 69

Subtracting, it becomes

15y = 45

y = 45/15

y = 3

Substituting y = 3 into equation 1, it becomes

2x + 9 × 3 = 38

2x + 27 = 38

2x = 38 - 27 = 11

x = 11/2 = 5.5
