Jennifer gets a salary of $12000 while David gets $8400 more per month. What is the ratio of the salaries of Jennifer and David?

1 answer:

8 0

Step 1
Jennif er's salary = $12000
Step 2
It is given that David gets $ 8400 more per month than Jennifer, therefore David's salary = 12000 + 8400 = $20400
Step 3
The fraction of the salaries of Jennifer and David = 12000 = 10 204 00 17
Step 4
Therefore the ratio of the salaries of Jennifer and David = 10:17

If m(x) = x+5/x-1 and n(x) = x — 3, have the same domain as (m • n) (x)

Yuri [45]

For this case we have the following functions:

$m (x) = \frac {x + 5} {x-1}\\n (x) = x-3$

By definition we have to:

$(f * g) (x) = f (x) * g (x)$

So:

$(m * n) (x) = m (x) * n (x)\\(m * n) (x) = \frac {x + 5} {x-1} (x-3)\\(m * n) (x) = \frac {(x + 5) (x-3)} {x-1}$

By definition, the domain of a function is given by the values for which the function is defined.

The domain of m(x) is given by all reals except 1.

The domain of n(x) is given by all reals.

While the domain of $(m * n) (x)$ is given by:

All reals, except the 1. With $x = 1$ , the denominator is 0 and the function is no longer defined.

Answer:

Domain of $(m * n) (x)$ is given by all reals except 1.

Solve the following equation and show all of your steps: x^2+x−1=0

DaniilM [7]

Quadratic formula since this trinomial is not factorable.
$\frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ \frac{ - 1 + - \sqrt{ {(1)}^{2} - 4(1)( - 1) } }{2(1)} \\ \frac{ - 1 + - \sqrt{1 + 5} }{2} \\ \frac{ - 1 + - \sqrt{6} }{2} \\ x = \frac{ - 1 + \sqrt{6} }{2} \\ x = \frac{ - 1 - \sqrt{6} }{2}$
