If water and oil are combined in a container, the resulting liquid is a(n)
a. mixture.
b. emulsion.
c. solution.
d. suspension.

The correct option is (B).

Step-by-step explanation:

Emulsion is an example of colloids in which particles of component are suspended in immiscible liquids. It is usually an suspension of two liquids which do not mix together. These liquids which do not mix together are called immiscible.

Where as mixture is made up two or more substance which are mixed together. In a mixture identity of substance remains unchanged.

Solution is defined homogeneous mixture of two or more compounds. In this one components completely get dissolves in another component.

Suspension is defined as solution where one component doesn't get dissolved in another component and forms two distinct layers when left undisturbed.

Hence ,the correct answer is option(B).

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
