What is the distance between (2, -4) and (9, -4)?
alexdok [17]

Answer:

7 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (9, - 4)

d = \sqrt{9-2)^2+(-4+4)^2}

   = \sqrt{7^2+0^2}

   = \sqrt{49}

  = 7

Irina18 [472]

The better option will be at DiscountsRUs 40% off on any purchase.

<h3>What is the discount?</h3>

The amount of money which is reduced on any product below its actual selling price is called the discount.

here we have two offers from the two stores Dominic had a coupon for 15 off his purchase at Save4You. At DiscountsRUs, there was a sale of 40% off on any purchase.

For a Dominic, the discount is fixed for any purchase that is if you purchase a $50 product or a $1000 product you will be getting only a $15 discount.

Now for the second store, the discount is given as 40% so if you purchase $50 your discount will be $20. If you purchase $1000 so 40% discount will be $400.

Therefore better option will be at DiscountsRUs 40% off on any purchase.
