Answer:
f(n) = -6n - 10.
Step-by-step explanation:
This is arithmetic sequence with first term a1 = -16 and common difference d = -6.
So f(n) = a1 + d(n - 1)
= -16 - 6(n - 1)
= -16 - 6n + 6
= -6n - 10.
Checking:
f(10) = -6(10) - 10 = -70.
There is 10,000 possible combinations for the numbers 0-9
Step-by-step explanation:
x=180°-109°=71° (Interior angles)
y= 71° (Alternate angles)
y= 180°- 65°=115° (Adjacent angles)
x= 65° (Corresponding angles)
