Answer:
11th term is 0
Step-by-step explanation:
30, 27 , 24 ,......0
a = first term = 30
Common difference = second term - first term = 27 - 30 = -3
nth term = a+(n-1)*d
a + (n-1)d = 0
30 + (n - 1) *(-3) = 0
30 + n*(-3) -1*(-3) = 0
30 - 3n + 3 = 0
-3n + 33 = 0
-3n = -33
n = -33/-3
n = 11
13. Is 18
15. Is 86
17 is 5
19 is 15
21 is 24
23 is 29
Answer: y = 1/2x - 9
Step-by-step explanation:
- y + 5 = 1/2(x - 8)
- y + 5 = 1/2x - 4 (distribute)
- y = 1/2x - 9 (subtract 5 from both sides)
