SORRY I TRIED GETTING A PICTURE BUT IT WOULDEN'T LET ME Mackenzie needs to determine whether the rectangles are proportional. Which process could she use? Check all that apply. A pre-image rectangle has a length of 4 and width of 3. An image rectangle has a length of 2 and width of 1.5.
She could compare the ratios of the sides of the pre-image to the corresponding sides of the image in the proportion StartFraction 3 Over 1.5 EndFraction = StartFraction 4 Over 2 EndFraction.
She could verify that adding the same number to each side in the pre-image does not result in the corresponding side length of the image.
She could verify that multiplying each side in the pre-image by One-half results in the length of the corresponding side in the image.
She could verify that subtracting the same number to each side in the pre-image does not result in the corresponding side length of the image.
She could just notice that all the sides in the pre-image are whole numbers so all the sides in the image should be whole numbers.

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
