2.) y=-3x-1 and if you look closely you’ll notice the line is going down making it negative and it’s going down by 3 so it’s -3x and when your looking for y just remember you’re looking for the point that’s on the line of y and here you can see the point is on -1 so there’s your answer.
I suppose the integral is
The integration region corresponds to a sector of a cirlce with radius 5 subtended by a central angle of π/4 rad. We can capture this region in polar coordinates by the set
Then 
, 
, and 
. So the integral becomes
First of all, its the jack of diamonds. Well, the king is worth 10 or 13. The jack is worth 11 or 10. The 3 is worth either 3 or 5. Depending on what you mean by value, the expression could be 13+11+3 or 10+10+5.
