You would solve using elimination.
y=1
x=-1
Y=(5x-4)/2 first move -2y to the other side to obtain a positive value and make y the subject
Since it asks you to estimate, you would round the 4.6 up to 5. The estimate volume would be 125 inches^3; answer C.
Example:
Linear absolute value inequalities all have a similar equation of |ax + b| < c, except they can be less than, greater than, less than or equal to, or greater than or equal to.
Hope this helped :)
Answer:
W > 0.5L
Perimeter:
2L + 2W < 180
2L + 2(0.5L) < 180
2L + 1L < 180
3L < 180
÷3 ÷3
L < 60
Length should be less than or equal to 60 inches while width should be greater than or equal to 30 inches.
