Answer:
ab = 1
Step-by-step explanation:
A Reciprocal of a number is a number which when multiplied by the original number yields the multiplicative number, 1.
So the reciprocal of x would be x⁻¹ or ¹⁄ₓ
The information we are given states that the sum of the two non-zero numbers a and b equals the sum of their reciprocals.
So we can write this into an equation and solve,
(See image)
Once we solve, we get the equation (ab-1)(a+b) = 0
We are given info that a+b≠0
So for the above equation to be true, ab-1 has to equal 0
For <em>this</em> to be true, the product ab must equal 1
Answer:
The commission would be $ 920.
Step-by-step explanation:
Given,
Sales in 1997 = $ 9500,
Since, there is a commision of 8 % on the first $ 7500 of sales, 16% on the next $ 7500 of sales, and 20% on sales over $ 15,000,
If x represents the total sales,
Commission for x ≤ 7500 = 8% of x = 0.08x,
Commission for 7500 < x ≤ 15000 = 8% of 7500 + 16% of (x-7500)
= 600 + 0.16(x-7500),
Commission for 7500 < x ≤ 15000 = 8% of 7500 + 16% of 7500 + 20% of (x-15000)
= 600 + 1200 + 0.20(x-15000)
= 1800 + 0.20(x-15000)
Thus, the function that shows the given situation,
Since, 9500 lies between 7500 and 15000,
Therefore, the commission would be,
f(9500)= 600 + 0.16(9500 - 7500) = 600 + 320 = $ 920
