MAT382H5 Chapter 3: Reading - A Stroll through Koenigsberg

I know The answer for these question , but the graph missed ,,,So >> The question here is to Graph the answers

Here is the answer

a) |2y+5|>1

so -1 <2y+5< +1

-6<2y<-4

so -3<y<2 answer

b) 7+ |3y-2| <= 10

|3y-2| <= 3

-3<3y-2<3

-1<3y<5

so -1/3 < y < 5/3

c) |6x+5| >= -5

5 > 6x+5 > -5

-10 < 6x < 0

-10/6 < x

d) |3x| < -1

not possible a positive quantity can not be negative

NOW JUST GRAPH .

Find the DOWNWARD flux of F = 〈x, y,z) across the plane z = 2 over the region D={(x,y)|0<=x<=1,0<=y<=1}
