NAFTA as an organization is very important for the three North American economies, the USA, Canada, and Mexico. It is basically a regional trade organization which has lifted the borders when it comes to trade, thus enabling free movement of goods between these three nations. This has resulted in rise of the economies of all three nations, as there were no trade barriers between them anymore. The companies where able to move their facilities and to operate in each of these countries, which brought them larger profits. The Canadian and the US economies became almost like one, as the companies managed to operate in both places, and to become major players in the market, this especially goes for the US companies that made Canada their home terrain.

5.Find the slope of a line perpendicular to

Lemur [1.5K]

Hi there!

When the slopes of two perpendicular lines are multiplied the outcome will be -1.

The slope is the number that is positioned in front of the variable x in the formula. In this case the slope of the given line is -2/5.

Let's call the slope of the perpendicular line m and take into account the given data of the question and my earlier explanation. We then find the following:

$- \frac{2}{5} \times m = - 1$
Divide both sides by - 2/5.

$m = \frac{ - 1}{ - \frac{2}{5} } = 2 \frac{1}{2} = \frac{5}{2}$
The answer is B.

The length of a rectangle is 9 less than 4 less than the width. The perimeter is 143. Find the width and length.

damaskus [11]

The formula for perimeter is 2l+2w. Since we know l=(w-4)-9, we can substitute this into the formula.

l=w-13

2(w-13)+2w=143

2w-26+2w=143

4w=169

w=42.25 units

Hope this helps!
