X^2 - 12x  = 61
Take half of the coefficient of the middle term (half of -12x), square this result, and then add, and then subtract, from -12x:

x^2 - 12x + (6)^2 - (6)^2     = 61

    (x-6)^2 - 36 = 61, and so   (x-6)^2 = 97

Note:  These results are all equivalent; choose the one you think best.

Kelly price sells college textbooks on commission. She gets 8 % on the first $7500 of​ sales, 16% on the next $7500 of​ sales, a
Solnce55 [7]

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,

f(x)=\left\{\begin{matrix}0.08x & x \leq 7500\\ 600+0.16(x-7500) & 7500 < x \leq 15000\\ 1800+0.20(x-15000) & 15000 < x\end{matrix}\right.

Since, 9500 lies between 7500 and 15000,

Therefore, the commission would be,

f(9500)= 600 + 0.16(9500 - 7500) = 600 + 320 = $ 920

Four consecutive positive prime numbers have a sum that is divisible by three. What is the smallest possible value of this sum?
LuckyWell [14K]

Answer:

36

Step-by-step explanation:

1 + 3 + 5 + 7 = 16

3 + 5 + 7 + 11= 26

These consecutive positive prime numbers above have sums that are not divisible by three.

5 + 7 + 11 + 13 = 36

This consecutive positive prime numbers above has a sum that is divisible by three: 36.

36 : 3 = 12
