Solve the equation by factoring. z2 − 6z − 27 = 0

Lisa [10]

Answer:

The answer is x= 9 and -3

You must fine 2 number that multiply to equal -27 and add to equal -6

(x-9) (x+3)

Then equal the parts of the binomial to zero

x - 9 = 0

x + 3 = 0

You must get x by its self.

When you do so, you'll have the answer as -3 and 9

Nutka1998 [239]

Assume x are Erica's classes & y are Bo's classes.
x+y=35
x=2y-13
Replacing the value of x into the first equation
2y-13+y=35
3y=35+13
y=16 classes
x=2*16-13=19 classes

A company that makes barber scissors has found that the sales volume for barber scissors is directly proportional to the size of

Mice21 [21]

Answer:

20,000 pairs of barber scissors.

Step-by-step explanation:

The sales volume V for barber scissors is directly proportional to the size S of the sales force and inversely proportional to the price P of the scissors.

In other words, we can write that:

$\displaystyle V = \frac{kS}{P}$

Where k is the constant of proportionality.

19,440 pairs were sold in 2013, when there was 54 salespeople and the price was $20 a pair. Hence, V = 19440 when S = 54 and P = 20. Substitute and determine the value of k:

$\displaystyle \begin{aligned} (19440) &= \frac{k(54)}{(20)} \\ \\ 19440 &= \frac{27}{10}k \\ \\ k &=\frac{10}{27}(19440) = 7200 \end{aligned}$

Hence, our equation is:

$\displaystyle V = \frac{7200S}{P}$

We want to determine the sales forecast with 50 salespeople and a price of $18 a pair. Hence, S = 50 and P = 18:

$\displaystyle \begin{aligned} V&= \frac{7200(50)}{(18)} \\ \\ &= 20000\end{aligned}$

In conclusion, 20,000 pairs of barber scissors can be expected to be sold.
