Real Number System
What is the real number system?
A series of categories to contain rational and irrational numbers.
The quotient of a number and -5, increased by 7 is at minimum 1.
x≤30
what is slope?
The steepness of a line, or the distance between two points.
solve. 6y-8-6-8y=4
y=9
What is mean?
The average of a data set.
All numbers are real. True or false?
True
