C. (-13,-13)
You take the x of the midpoint and equal it to the formula of the midpoint so it will be -6 = 1+x/2 so 1st you times 2 by 6 because you wanna get rid of 2 so it will -12 Then when you move 1 so x is alone it will be -1 so -12-1= -13
Same thing for y
What exactly do u want us to do?
X-small bag
x+0.9-large bag
5(x+0.9)+3(x)=17.22
5x+4.5+3x=17.22
8x=12.72
x=1.59
the small bag costs 1.59 while the big bag costs 2.49
hopw this helps :)
