Graph the three inequalities

r+y =5

8r+12y>=120

My teacher said this: I need the graph of the three inequalities and the shading for each with the answer region identified. I don't know how to do this.

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

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
