Ahot air balloon leaves the ground and rises to an elevation of 1,100 feet. during the next 30 minutes, it descends 500 feet, rises 950 feet, descends 375 feet, and finally passes over a school. what is the elevation of the balloon when it passes over the school. a. 1,025 feetb. 1,100 feetc. 1,175 feet

1100-500=600 600+950=1550 1550-375=1175 so C is your answer

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
