The vertices are L(3,-1) M(7.-3) and N (6,3) find the vertices after a 90° rotation about each of the points L, M, and N? Please help I need to get this done soon!

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

16
