55: 35 the final cost of a sale item is determined by multiplying the price on the tag by 75% which best describes the function that represents the situation item cost price on the tag, x $10 $20 $30 $40 final cost 0.75(10) 0.75(20) 0.75(30) 0.75(40) it is inear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant it is inear because the function is continuous dit is onlinear because the final cost is determined by multiplying each price tag by 0 75 it is nominear because the price tag and final cost columns do not have the same common difference save and exit ^=*

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
