Answer:

f(6) =6^2 - 2(6)

f(6) = 36 - 12

f(6) = 24

f(-3) = (-3)^2 - 2(-3)

f(-3) = 9+6

f(-3) = 15

f(-4) = (-4)^2 - 2(-4)

f(-4) = 16 + 8

f(-4) = 24

A new television set was recently purchased for the common room in a residence hall for $436.80 including tax the tax rate is 4%
garri49 [273]

Answer:

The price of the television before taxes is $420

Step-by-step explanation:

* Lets explain how to solve the problem

- The purchased price = cost price +  taxes

- A new television set was recently purchased for the common room

 in a residence hall for $436.80

- This price including tax

- The tax rate is 4%

- We need to find the price of the television before taxes

* <em>Lets solve the problem</em>

- Assume that the price of the television before tax is 100%

∵ The tax rate is 4%

∵ The price after tax = price before tax + tax

∵ The price before tax = 100%

∴ The price after tax  = 100% + 4% = 104%

∵ 104% equivalent to $436.80

∴ 100   ⇒   ?

  104   ⇒   436.80

- <em>By using cross multiplication</em>

∴ ? = \frac{(436.80)(100)}{104}=420

∴ The price of the television before taxes is $420

A line passes through the points A(n,4) and B(6,8) and is parallel to y=2x-5. What is the value of n?​
Lady_Fox [76]

The slope of <em>y</em> = 2<em>x</em> - 5 is 2. Parallel lines have the same slope, so the slope of the line through the given points <em>A</em> and <em>B</em> is also 2. This means

(8 - 4) / (6 - <em>n</em>) = 2

Solve for <em>n</em> :

4 / (6 - <em>n</em>) = 2

4/2 = 6 - <em>n</em>

2 = 6 - <em>n</em>

<em>n</em> = 6 - 2

<em>n</em> = 4
