There are four kinds of road signs in a certain town. The number of each kind is shown. What is the ratio of the number of school signs to the number of stop signs? Illustrations of four road signs are shown including a stop sign, railroad crossing sign, yield sign, and a school sign. The number 10 is above the stop sign. The number 3 is above the railroad sign. The number 2 is above the yield sign. The number 9 is above the school sign.

A. 9 to 10
B. 10:9
C. Start Fraction 10 over 24 End Fraction
D. 9:24

asking for a friend me and him idk

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

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
