The inequality -y<3x-5 by multiplying by -1 becomes y>-3x+5. 1. Draw line y=-3x+5. When x=0, y=5, when y=0, -3x+5=0, x=5/3. 2. Choose the correct semiplane, substituting (0,0) into the inequality. Since 0 is not greater than 5, you can conclude that point (0,0) isn't a solution and doesn't belong to the shaded area. 3. The correct answer is first choice
The dimensions would have to be 20 x 5 as the model holds the same amountfor each side, and because 5 is larger than 4 its used as the models stand. Hope it helps! :)
