Mrs. duggal teaches 25 students. out of these 25 students, 16% wear glasses. this grid represents the 25 students in mrs. duggal's class. shade the squares to represent the number of students who wear glasses.

16 percent of 25 is 4 so shade 4 squares. 

Hello! So, there are 25 students is Mrs. Duggal's class. To find the amount of students that wear glasses in the class, mutliply the number of students (25) by the percentage, in this case 16% (0.16). 25 * 16% (0.16) is 4. So you have a grid that represents 25 squares. Out of those 25 squares, you would shade 4 of them, and that would represent the students that wear glasses.

Idon’t exactly understand but i think dbc=rst

and y≤ -x +4 .

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

y≤ -x +4 .
