Answer:

Step-by-step explanation:

Distance=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}\\\\d_{3}=\sqrt{(2-[-1])^{2}+(0-4)^{2}}\\\\ =\sqrt{(2+1)^{2}+(-4)^{2}}\\\\ =\sqrt{(3)^{2}+(-4)^{2}}\\\\=\sqrt{9+16}\\\\ =\sqrt{25}\\\\ =5

a cell phone company is giving a 20℅ discount on all phone accessories which expression can used to find the sale price of an it
Sholpan [36]

Answer:

The expression that can be used is 0.80x

Step-by-step explanation:

Let

x ----> original price of an item

Remember that

100\%-20\%=80\%

That means---> the sale price is 80% of the original price

To find out the sale price, determine the 80% of the original price

80\%=80/100=0.80 ----> percentage in decimal form

Multiply the original price by the percentage in decimal form to obtain the sale price

so

0.80x

Lynna [10]
The slope of the line that passes through the points (14/5) and (20, -4), so you take y-y/x-x so you substitute the y's in for 5 and -4 and x in for 14 and 20.

5--4/ 14-20
9/-6
Then you make the fraction smaller!
