Answer:
y=2x+1
Step-by-step explanation:
6(y+3) = 72
6y + 18 = 72
6y = 72 - 18
6y = 54
y = 54/6
y = 9
17. 3(4-2(-2))......3(2(-2)).....3(-4).....-12
18. 2(-3)-3(3)......-6--9......-6+9.....3
19. 1,234.6
Answer:
a30 = 96
Step-by-step explanation:
-20,-16,-12,-8,-4
We are adding 4 each time, which is the common difference
-20+4 = -16
-16+4 =-12
The formula for an arithmetic sequence is
an = a1 +d(n-1) where a1 is the first term and 4 is the common difference
an = -20 +4(n-1)
We want the 30th term
a30 = -20+4(30-1)
a30 = -20 +4(29)
= -20 +116
= 96
