Answer:

B -4/5

Step-by-step explanation:

The slope of line D is given by

m = (y2-y1)/(x2-x1)

    = (6-1)/ (5-1)

    =5/4

We want the slope of the line perpendicular

That would be the negative reciprocal

- (4/5)

Mamont248 [21]

Answer:

After using the offer the carpet would cost Ahmed $180.

Step-by-step explanation:

Given:

Cost of the carpet = $240

Discount percent = 25%

We need to find the cost of the carpet after discount.

Solution:

First we will find the Discount cost.

Now we know that;

Discount cost is equal to Discount percent multiplied by Cost of the carpet divided by 100.

framing in equation form we get;

Discount cost = \frac{25}{100}\times 240 = \$60

Now we will find the Cost of the carpet after discount.

Now we know that;

Cost of the carpet after discount is equal to Cost of the carpet minus Discount cost.

framing in equation form we get;

Cost of the carpet after discount = \$240-\$60= \$180

Hence After using the offer the carpet would cost Ahmed $180.
