In this question, we have to fin the line of intersection of the planes A and QRV.
We have to see the given figure and find the line on which the two planes A and QRV meets.
Lines SR,TS, WT and WQ are not on plane QRV.
The only line which passes through both planes is QR.
And that's the line of intersection of the two planes.

14.I can't see the whole graph, so you need to do it yourself. Add up everyone's age and divide by the amount of people on the graph. That will give you the average.
Remember, parenthaees are like < and > and brackets ar like ≤ and ≥
domain is how far the x values go
x is left to right
we see they go from -3 to 5, with a filled in dot at -3 and empty dot at 5
means include -3 but not including 5
so like -3≤x<5
or in interval notation
[-3,5) is the domain
range
highest to lowest y value
range is from y=3 to y=-1
we gots full dots so we use brackets
range is [-1,3]
Domain=[-3,5)
Range=[-1,3]
B. read above and understand it
The answer is A
Domain: (0, infinity)
Range: ( - infinity, infinity)
