Answer:
a₈ = - 10935
Step-by-step explanation:
the nth term of a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio
here a₁ = 5 and r = = = - 3 , then
a₈ = 5 × = 5 × - 2187 = - 10935
Answer:
91
Step-by-step explanation:
Substitute 4 in place of x
f(4)=20*4+11
f(4)=80+11
f(4)=91
He can conclude that the system of equations has no solution since one equation in it always results with false equivalency.
Hope this helps.
