which figure represents the image of parallelogram lmnp after a reflection across the line y = x?figure afigure bfigure cfigure d

figure C

When a point is reflected across the line y = x the x and y coordinates change its place. These are the coordinates of vertices of the figure C. Therefore, figure C represents the image of parallelogram LMNP.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
