Answer:
Step-by-step explanation:
The n-th term is given by ...
an = a1 + d(n -1)
for common difference d and first term a1.
You have a sequence with a first term 4 and a common difference of 6-4=2, so the formula is ...
an = 4 + 2(n -1)
__
Using n=8, we find ...
a8 = 4 + 2(8-1)
a8 = 18
Consider, pls, this option:
(the sum of three angles must be 180°)
(60+x)+(x+85)+55=180;
2x=-20;
x= -10.
Note, that 60+85+55=200 > 180!
60+x=50° and x+85=75°.
If to check the sum.: 75+50+55=180°
Answer:
I think x is 14
Step-by-step explanation:
15+4=19
19-5=14
F(x) = 500x-8000
500 times the number of years (x), subtracted by the original price (8000)
