Answer:
The correct answer is:
Option 2: Yes, because the slopes of lines are negative reciprocals.
Step-by-step explanation:
Given equations of lines are:
Line p: x+2y=1
Line q: y=2x+1
We can determine if two lines are parallel or perpendicular by comparing the slopes of line.
Slope intercept form of line is given by the formula
Equation of line q is already in slope intercept form.
We have to convert the equation of line p in slope-intercept form
Slope of line p = 2
Slope of line q = -1/2
We can see that
The product of slopes of both lines is -1, hence, the lines are perpendicular.
Hence,
The correct answer is:
Option 2: Yes, because the slopes of lines are negative reciprocals.
Answer:
I would say that it is 3/2
Step-by-step explanation:
Answer:
60 degrees.
Step-by-step explanation:
BC is parallel to the x axis (because B and C have the same y-coordinate).
Slope of AB is 3/√3 = √3
so the angle AB makes with the axis = angle it makes with BC
= arctan(√3)
= 60 degrees.

Answer:
t < 0 and t > 140
Step-by-step explanation:
It is given in the question that fluid is not a liquid if its temperature is above 140°C or below 0°C.
So, the inequality that satisfies the temperature at which the fluid is liquid will be given by 140 ≥ t ≥ 0.
Now, the compound inequality for the temperature t when the fluid is not liquid is t < 0 and t > 140. (Answer)
