Answer:
SAS Congruence Postulate
Step-by-step explanation:
Given RN=NQ and MN=PN
Also if we clearly observe we can say that ∠MNR=∠PNQ (When two lines meet the opposite angles are equal).
By SAS congruence postulate we can say that ΔRMN and ΔQNP are congruent.
SAS congruency postulate states that if two sides along with the included angle are equal of two triangles then those two triangles are congruent.
Answer: its a relation only :))
Step-by-step explanation: bc of that rule saying that there is only one output for every input there for not a function ( not a one to one function)
This function is defined from -inf to inf for all real numbers of x. The only reason a function would have a break in the domain and range would be if there was a radical, fraction, ln, etc(any operand that has a restriction)
A) i) - 1 + 2 + -3 = -2
ii) 4 - 9 = -5
b) i) xy
ii) y * y+1 ??
