Find the quotient. x + 7 x ÷ 9 x

kicyunya [14]

The first step for solving this expression is to write the division as a fraction.
x + $\frac{7x}{9}$ × x
Calculate the product.
$\frac{7x X x}{9}$
Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:
$\frac{7 x^{1}X x^{1} }{9}$
Now multiply the terms with the same base by adding their exponents.
$\frac{7 x^{1+1}}{9}$
Finally,, add the numbers together to get your final answer.
x + $\frac{7 x^{2}}{9}$
Let me know if you have any further questions.

Jay makes a base salary of $2000 per month. Once he reaches $50000 in total sales, he earns an additional 5% commission (salary)

ki77a [65]

Answer:

$j(s) = 0.05s -500$

Step-by-step explanation:

Given

$Base\ Salary = 2000$

$Commission = 5\%$ on Sales over 50000

Required

Determine the function j(s) for sales over 50000

Represent the total sales in a month with s.

Sales over 50000 in that month will be: s - 50000

So, the function j(s) is:

j(s) = Base Amount + Commission * Sales over 50000

$j(s) = 2000 + 5\% * (s - 50000)$

Convert % to decimal

$j(s) = 2000 + 0.05 * (s - 50000)$

Open bracket

$j(s) = 2000 + 0.05 * s - 0.05 * 50000$

$j(s) = 2000 + 0.05s - 2500$

Collect Like Terms

$j(s) = 0.05s - 2500 + 2000$

$j(s) = 0.05s -500$

Log based question, i just need help with parts b and c

Tanya [424]

Answer:

b) There is translation 3 units to the right and 1 unit up

c) The domain is {x I x > 3}

The equation of the asymptote is x = 3

Step-by-step explanation:

* Lets revise the rule of the translation

- If the function f(x) translated horizontally to the right

by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left

by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up

by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down

by k units, then the new function g(x) = f(x) – k

* Now lets solve the problem

b) ∵ f(x) = $log_{2} (x-3)+1$

∵ The parent function is $log_{2} x$

∴ x is changed to (x - 3), that means there is a translation 3 units

to the right

∵ We add the parent function by 1, that means there is a translation

1 unit up

* There is translation 3 units to the right and 1 unit up

c) To find the domain of the function, find the values of x which

make the function undefined

∵ $log_{2}(0)$ is undefined

∴ x - 3 can not be 0

∵ x - 3 = 0 ⇒ add 3 to both sides

∴ x = 3

∴ The domain of the function is all real number greater than 3

* The domain is {x I x > 3}

∵ x can not be 3

∴ There is a vertical asymptote, its equation is x = 3

* The equation of the asymptote is x = 3

# Look to the attached graph for more understand for the domain

and the equation of the asymptote
