I'll solve for y
xy+(4(20))>x-5y(2+9-7)
xy+4(20)>x-5y(2+9-7)
xy+4(20)>x-5y(4)
xy+4(20)>x-20y
xy+80>x-20y
xy+20y+80>x
y(x+20)>-80+x
y>(-80+x)/(x+20)
Y=17 is not a linear function,the term refers to two distinct but similar notions
<span>We know that 1 cm3 is 1 cm * 1 cm * 1 cm, so in inches:
1 cm3 = 1 inch3/2.54^3 cm3 = 1/2.54*1/2.54*1/2.54 = 1/16.387 = 0.061 inch3
Another way to solve is:
1 inch = 1 inch/2.54 cm = 0.3937 cm
Then 1 inch3 = 0.3937^3 cm = 0.061 inch3</span>
