24. explain what is meant by a subset.
choose the correct answer below.
a. a subset is the set that is completely contained within every other set. there cannot be any
elements in the subset which are not also in another set.
ob. a subset is a set that is completely contained within another set. there cannot be any
elements in a subset which are not also in that other set
oc. a subset is a set that is completely contained within another set and has at least one
element. there cannot be any elements in a subset which are not also in that other set.
od. a subset is a set that is completely contained within another set and is not equal to that
other set. there cannot be any elements in a subset which are not also in that other set.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
