Answer:
Answer 3 (-6x-2y=12)
Step-by-step explanation: Turn to slope form to check
First- Add the 6x from both sides
-2y=6x+12
Second- Divide by two on both sides
y= -3x-6

826 1/25
Answer:
0.053246
Step-by-step explanation:
log(26)−log(23)
=1.414973−log(23)
=1.414973−1.361728
=0.053246
Answer:
Step-by-step explanation:
<u>Time needed if they work together:</u>
- 1 / (1/11 + 1/9) =
- 1/ (20 / 99) =
- 99/20 ≈ 5 hours
Answer:
y = -1/3x + 8
Step-by-step explanation:
If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.
(basically if one is say -2/3, the other is 3/2. just flip it upside down)
So this slope is 3, so the new slope should be -1/3
The equation is now y = -1/3x + b
To find b, substitute (-9,5) in the equation
y = -1/3x + b
5 = -1/3(9) + b
5 = -3 + b
8 = b
So the equation is y = -1/3x + b
