The robber stole 280 dollars' worth of one-dollar bills. he also stole some 100-dollar bills, 50-dollar bills, and 20-dollar bills. which expression could represent the amount of money that was stolen?

the answers are in the images, i received 100% on this assignment. hope this !

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.

step-by-step explanation:

mark brainliest!

for future students the answer is b

hope i
