All of the given numbers are both real and rational, and so all of their respective squares are also real and rational.
You wanna cross out numbers if they can both divide by the same number. then multiply the numbers in the same row together
Answer:
yes
Step-by-step explanation:
Answer:
lines b and c are perpendicular
Step-by-step explanation:
Use slope
slope for parallel is the same
slope for perpendicular is negative reciprocal
line a slope- 1-3/-2-0 is -2/-2 or 1
line b slope- 1-4/4-6 is -3/-2 or 3/2
line c slope- 3-1/1-4 is 2/-3 or - 2/3
none are the same so none are parallel
- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular
Algebraically, that will be expressed as:
