Step-by-step explanation:
Here, in step format, is how to solve a system with three equations and three variables:
Pick any two pairs of equations from the system.
Eliminate the same variable from each pair using the Addition/Subtraction method.
Solve the system of the two new equations using the Addition/Subtraction method.
9. Given A = {1, 2, 3, 4, 5, 6, 7, 8, 9} and B = {2, 4, 6, 8}, what is A∪B?
PtichkaEL [24]
A union B is the set containing all elements in set A and set B there for A union B is the set {1 2 3 4 5 6 7 8 9}
The answer could be 32^(-2)
Answer:
5) EG=HG because it's corresponding part of congruent triangles are congruent (CPCTC)
