Answer:
8x-7y=6
or, -7y=-8x+6
or, y=8x/7-6/7
so the slope is 8/7
8x-y=-8
or, -y=-8x-8
or, y=8x+8
So the slope is 8
Both has different slope and they don't satisfy the property of being perpendicular to each others, so they're neither parallel nor perpendicular.

Step-by-step explanation:
Answer:
Option a) 1.6 .
Step-by-step explanation:
We are given that 142 subjects were treated with acupuncture. The numbers of migraine attacks for the treatment group had a mean of 1.8 and a standard deviation of 1.4 which means;
Sample Mean, = 1.8 , Sample standard deviation, s = 1.4 and Sample size = 142.
Now, 95% confidence interval estimate of the mean number of migraine attacks for all people treated with acupuncture is given by;
⇒
So, the lower bound = = 1.56 ≈ 1.6
Therefore, option A is correct.
Answer:
the first on is y=30+1.5x and megawatch is y=100+0.90x
Step-by-step explanation:
$1.50 is the cost of 1 pound of oranges. You have to divide 4.50 by 3 because you have to get to one pound cost. Sorry if i am wrong. I am really sorry if I am wrong.
