What is the slope of a line perpendicular to the line y = −14x – 1?

Answers

Answer:

        m = ¹/₁₄

Step-by-step explanation:

y=m₁x+b₁   ⊥   y=m₂x+b₂   ⇔    m₁×m₂ = -1

{Two lines are perpendicular if the product of theirs slopes is equal -1}

y = -14x - 1   ⇒   m₁ = -14

-14×m₂ = -1        ⇒    m₂ = ¹/₁₄

So, the slope of a line perpendicular to the line y = -14x - 1 is m = ¹/₁₄

Sara bought a computer that was originally priced at $896. The computer was on sale for 12% off. When she bought the computer, a 7% tax was added to the sale price. How much did Sara spend on the computer?
(Round to the nearest cent)

Answers

Hm 1 second let me write the work down for this problem

Answer:

$843.67

Step-by-step explanation:

1. Calculate the discount that was taken off from the original price.

$896 x 12% = $107.52

2. Subtract the discount taken off from the original price. This gives you the total paid AFTER the discount was taken.

$896-$107.52= $788.48

3. Calculate the tax amount by multiplying the discount price by the tax rate.

$788.48 x 7% = $55.19

4. Add the tax amount back to the discount price.

$788.48 + $55.19 = $843.67
