Define the set X = {(x,y)|x > 0,y ≤ √x}.
Kitty [74]

The set X is convex.

In geometry, a subset of an affine space over the real numbers, or more broadly a subset of a Euclidean space, is said to be convex if it contains the entire line segment connecting any two points in the subset. A solid cube is an example of a convex set, whereas anything hollow or with an indent, such as a crescent shape, is not. Alternatively, a convex region is a subset that crosses every line into a single line segment.

b)The set X is convex as any two points on the set X is included in the whole set as x>0. So a line joining any two points on the set X is completely inside the set x.

c)set X is not a closed set as the compliment of the set is not an open set.

d)Set X is not bounded. If a set S contains both upper and lower bounds, it is said to be bounded. A set of real numbers is therefore said to be bounded if it fits inside a defined range. hence set x is not bounded.

- 2y + 3 = - 4y<br> The solution set is what???
lianna [129]

Answer:

Y=-3/2

Step-by-step explanation:

-2y+3=-4y

Move constant to the right  by adding its opposite to both sides

-2y+3-3=-4y-3

Eliminate the opposites

-2y=-4y-3

collect the like terms

-2y+4y

collect the like terms

(-2+4)y

Calculate the sum

2y=-3

divide both sides of the equation by 2

2y÷2=-3÷2

Any expression divided by itself equal 1

y=-3÷2

y=-3/2
