Answer:
x<0
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form: x<0
Find the slope of the line using the equation (y1-y2)/(x1-x2), which is change in rise over change in run. use any two points, for example (2,-2) and (3,-1). using the formula, (-2-(-1))/(2-3) is the rate of change, giving you -1/-1 as the slope, which is -1. the rate of change is -1.
Answer: 32760 ways.
Step-by-step explanation:
To solve this, we first determine the number of ways to select 4 countries from 15, we calculate number of ways to visit these 4 places then we multiply.
Selecting number of ways to choose 4 cities from 15 is by using the combination formula, which becomes 15C4
Number of ways to visit these 4 cities = 4!
Hence,total number of ways of visiting these 4 cities = 15C4 * 4! = 32760ways
