Diana and Sean are considering the quadrilateral with coordinates Q(-2,4), R(1,5), S(2,2), and -1,1). They already determined the sides of the quadrilateral are perpendicular and agree that QRST is a rectangle. However, Sean believes QRST is also a
square.
Which set of work correctly determines whether Sean is correct?

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

dont know

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road

it is c!
