if the formula P-0.5643y - 1092.57 can be used to predict average price of a theater ticket after 1945. For what years will the average ticket price be atleast $47.00 = y is the actual year?
Perimeter = 2(length+width)
If length=12 inches, width=x inches,
then
Perimeter = 2(12+x)
For perimeter≤44 inches,
we substitute perimeter by its expression
2(12+x) ≤44
If length=12 inches, width=x inches,
then
Perimeter = 2(12+x)
For perimeter≤44 inches,
we substitute perimeter by its expression
2(12+x) ≤44
