Find the maximum value of the function for the polygonal convex set determined by the given system of inequalities. 8x + 2y>36
-3x+6y<27
-7x+5y>-18
f(x, y)=9x+5y

a. the maximum is at (-3,6)
b. the maximum is at (-3,2)
c. the maximum is at (9,9)
d. the maximum is at (8,2)

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
