660 is the correct answer. Hope this helped!
-TTL
Y-y1= m(x1-x2)
using this formula
the answer is d
because slope has to remain the same if its parallel
See it up on brainly it should give you your answer that you need!!
This is a geometric sequence with common ratio (r) = 2.
an = ar^(n - 1)
a4 = a(2)^(4 - 1) = a(2)^3 = 8a
8a = 80
a = 80/8 = 10
7th term (a7) = 10(2)^(7 - 1) = 10(2^6) = 10(64) = 640
