Answer:
= 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
y + 2x = 2 ( subtract 2x from both sides )
y = - 2x + 2 ← in slope- intercept form
with slope m = - 2
given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
=
Answer:
No, that is not possible
Explanation:
P = 2L + 2W
Insert numbers into equation
p=(2)(20)+(2)(11)
Step 1: Simplify both sides of the equation.
p=(2)(20)+(2)(11)
p=40+22
p=(40+22)(Combine Like Terms)
p=62
p=62
The perimeter is 62, not 64, so the perimeter can't be 64 if the length 20 and the width is 11.

The price of the board game before the markup is $21.50.
<h3>
What is the cost before the markup?</h3>
Percentage can be described as a fraction an amount that is usually expressed as a number out of hundred. The sign used to represent percentages is %.
When the price of an item is marked up, it means that the price of the item has been increased by a predetermined percentage. In this question, the price of the board game is increased by 25%.
Price of the item before the mark up = price the retailer sells / ( 1 + percentage)
$26.88 / 1.25 = $21.50
