Matthew has a 20-gallon fish tank full of water
that he needs to move from one room to
another. He pours out all the water.
•The fish tank is a right rectangular prism.
•The fish tank weights 210 pounds when it is filled with water.
•The dimensions of the water inside the fish tank are 34 inches by 12 inches by 12 inches.
•1 cubic foot of water weights 62.4 pounds.
Find the weight of the fish tank when it is empty, to the nearest pound.

answer: f true

step-by-step explanation:

it is c, trust i got your back lol

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
