A 1 = 8, a 9 = 56
a 9 = a 1 + 8 d
56 = 8 + 8 d
8 d = 48
d = 6 ( common difference )
a 22 = a 1 + 21 d = 8 + 21 · 6 = 8 + 126 = 134
SO the answer is the 22nd term is 134
I really hope this helps!
It would be 8 inches, because for this you just have to find the greatest common factor between all three numbers which is 8
Answer:
d. y+8=2(x-4)
Step-by-step explanation:
There are 2 important parts to this question. First, understanding which slopes are perpendicular. The negative reciprocal of a number will be perpendicular to it. So, since the original slope is -1/2 the new slope should be 2.
Then, remember what the point-slope formula is. The point-slope formula is: 
. So if you plug in the point and slope the new equation looks like, 
. Then, simplify for the final answer of 
.
2 divides both numbers, so divide both numbers by 2 to get 3 and 7. These are relatively prime, so 2 is the gcd. The lcm is 6*14/2=42.
