Answer from: cocoapop

585/3 = 195 students

Step-by-step explanation:Each group of three created (or used) 9 pictures, so that means three pictures per student.

Dividing 585 students by 3 pictures per student means that there are 585/3=195 students.

Answer from: ijohnh14

Students(s) = 192.

Step-by-step explanation:

Eq:

3s + 9 = 585 (each group of 3 wrote 9 each, so for every group + 9. S = students and 585 is altogether.)

Isolate the 3s by doing the inverse (-) of addition and we do that by subtracting 9 from itself and 585.

Eq: 3s = 576

Lastly, isolate the s by dividing 3 (inverse of *)

Eq:

576

___

( s = 192 )

Answer from: Quest

$y> \frac{1}{3}x$ 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 = $\frac{1-0}{3-0} = \frac{1}{3}$ .

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

plugging slope m= $\frac{1}{3}$ and b=0 in slope-intercept form y=mx+b, we get

$y=\frac{1}{3}x$ .

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

$y> \frac{1}{3}x$ .

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

slope of the solid line would be = $\frac{4-1}{0-3} = \frac{3}{-3}=-1$ .

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 .
Write a system of inequalities to represent the shaded portion of the graph.
