Step-by-step explanation:
the sequence is arithmetic due to the common difference that is equal
d=11-15=7-11=-4
a(n) = a1 +(n-1)d
a1=15
Then :
a(n) = 15+(n-1)-4
hope this helps
Answer:
y>6
Step-by-step explanation:
Simplify so 5y-2(y)-2(4)>10
3y-8>10
3y>18
y>6
Answer:
Given : PS = QR
∠PRS = ∠RPQ
PR = PR (On the same base)
Proof / Reason :
∠PRS = ∠RPQ (R)
PS = QR (H)
PR = PR (S)
Therefore, Triangle PRS is congruent to Triangle RPQ
∠PSR = ∠RQP By C.P.C.T. ( Congruent Parts Of Congruent Triangles)
