Answer:
6/7
Step-by-step explanation:
Your first step will be to find the slope of Line C. Using the slope formula of 
, the slope of Line C is 
.
If Line D is perpendicular to C, that means the slope is the negative reciprocal of Line C. So, that means the slope is 6/7.

Answer:
A: 66/21
E: 22/7
Step-by-step explanation:
The offered choices reduce to 3 1/7 or to 3. The best approximations of those given are the ones that reduce to 3 1/7.
A: 66/21 = 22/7 = 3 1/7
B: 60/20 = 3
C: 21/7 = 3
D: 45/15 = 3
E: 22/7 = 3 1/7
___
<em>Comment on pi approximations</em>
The ratio 22/7 differs from π by about 0.04%. A better approximation is 355/113, which differs from π by about 0.000008%. The approximation 3.14 differs from π by about 0.05%.
Answer
0.44
Step-by-step explanation:
Convert to a fraction, then convert to a decimal by dividing the numerator by the denominator.
Distribute 2 and remove parentheses :
1/2x+8=3x-6
Multiply both sides of equation by 2:
x+16=6x-12
Move terms:
x+16-6x=-12
x-6x=-12-16
Collect like terms:
-5x=-28
Divide both sides:
x=28/5
Answer:
y = - 1/3 +2
Step-by-step explanation:
✯Hello✯
↪ first we need to rearrange this so the answer is equal to Y
↪ -3x on both sides
↪ 9y =-3x+18
↪ then divide by 9 to get y on its own
↪ Then we can simplify the answer -3x+18/9 further so the 2nd option is the answer
