First, we can graph these inequalities out. As you can see in the picture, the three vertices where the inequalities all connect form a triangle. We can check each of these vertices to find our minimum and maximum.

First, we have (3,7). 4y-3x = 4(7)-3(3)=28-9=19

Next, for (3, -3), we have 4y-3x = 4(-3)-3(3) = -12-9=-21

Finally, for (0.5, 2), we have 4y-3x=4(2)-3(0.5)=8-1.5 = 6.5

Our maximum is 19 when x=3 and y=7 and our minimum is -21 when x=3 and y = -3

chubhunter [2.5K]

3 hours and 20 minutes minus 1 hour and 48 minuets equals an hour and 32 minutes. There are 60 minuets in an hour and 60 divided by 32 is 0.53. This means that your final answer is:

Answer:

1. 40.97 2. 52.93 3. 32.00 4. 26.00

Step-by-step explanation:

remember that area =1/2 * b * h so to find base, you can make it the subject of formula i.e

b =area *h/2

or in the caseof h you can do

h= area * b/2
