Danica is arranging flowers for a party. on each table, t, there will be a vase of 9 flowers and 3 bowls of flowers with f flowers inside. danica needs an additional 12 flowers for a cake topper. this situation can be written as the following expression: 9t + (3f)t + 12 how many flowers should danica purchase if she has 21 tables with 3 flowers in each bowl?

answer: what do you mean

i think it is 18

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.
