Y=2x+3
put x =0 onetime then y=3
now put y =0 2x+3
x= -3/2
2.75+5*1.65=11 kg weight of the box with laptops.
p=40+(11-5)*3.15=58.9
The cost to ship the packed box is $58.9
6x – 4y = 9
4y = 6x - 9
y = 6/4 x - 9/4
y = 3/2 x - 9/4 this line has slope = 3/2
perpendicular line, slope is opposite and reciprocal so slope of this line = -2/3
answer:
A. y= - 2/3 x - 4 (only this line has slope = -2/3)
Your answer is -43/6
1/12(4+6x3)-9
=1/12(22)-9
=11/6-9
=11/6-54/6
=-43/6
