Answer:
11+y > -33
Step-by-step explanation:
Given:
2009 : 3,500 population
decrease of 2.2% per year.
100% - 2.2% = 97.8%
2014 - 2009 = 5 years
3,500 * (0.978)^5 = 3,500 * 0.89473 = 3131.57
The bird population in 2014 will be 3,131.57 or 3,132.
Answer:
Coordinate plane
Step-by-step explanation:
The two dimensional plane made up by the intersection of a vertical (y-axis) and a horizontal (x-axis) perpendicular lines that cross each other once at the zero point mark known as the origin is called the Cartesian plane or coordinate plane. The origin is labeled letter O with coordinates 0,0
The Cartesian plane is used to plot graph lines and points so as to present algebraic ideas in a visual form and to form as well as interpret ideas in algebra.
