Answer:
That's strange. (-1/2, 5) would work for both if only the top equation had a less than or equal to sign. If all else fails, just puts c as your answer lol
Step-by-step explanation:
Given:
Line A: 
Line B: 
Line C: 
Line D: 
To find:
Which lines are perpendicular
Solution:
General equation of a line:
y = mx + c
where m is the slope and c is the y-intercept.
Slope of line A = 
Slope of line B = 
Slope of line C = 2
Slope of line D = 
<em>Two lines are perpendicular if their slopes are negative reciprocal of one another.</em>


Negative reciprocal of
is 2.
Therefore line B and line C are perpendicular lines.
Answer: it will be 45, but for some reason it’s not in your answer choices
Step-by-step explanation:
Answer:
8 quarts
Step-by-step explanation:
There are 4 quarts in a gallon. If 1/3 of a gallon cover 1/6 of a wall, then an entire gallon will cover 1/2 of the wall. This means that 2 gallons will completely cover the wall. 2 gallons equals 8 quarts.
