Describe the slope of the line<br> Find the slope
Dmitry_Shevchenko [17]

Answer:

Question one: Zero slope
Question two: m=\frac{0}{4}

Step-by-step explanation:

Given the following questions:

<u>Question one:

</u>The following line is what you call a "zero slope." Zero slopes are lines that are neither decreasing or increasing and remain at a constant or just a straight line.

Question two:

Point A = (-2, -3) = (x1, y1)
Point B = (2, -3) = (x2, y2)

Using the formula for slope or rise over run we will solve and find the slope of this line.

m=\frac{y2-y1}{x2-x1}
m=\frac{-3--3}{2--2} =\frac{0}{4}
m=\frac{0}{4}

The slope of this line is "0/4."

Hope this helps.

If 75 percent of the employees of a certain company take a winter vacation, 40 percent take a winter and a summer vacation, and
anyanavicka [17]

Answer: 5%

Step-by-step explanation:

The number of employees that took Winter vacation = 75%

The number of employees that took Both winter and summer vacation = 40%

The number that took Neither = 20

The total number of employees (%) =Winter + Summer - Both + Neither = 100%

75%+ Summer - 40%+ 20%= 100%

Solving for Summer = 45%

Now we are interested in the employees that took summer but not winter = Summer only = Summer - Both(i.e. summer overlap with winter) = 45%-40%= 5%
