He concluded that a heavier object dropped from the same height as a lighter object will land

They will land at the same time.

Step-by-step explanation:

According to Gallileo's test where he dropped two balls (one heavier than the other) from the same height and they landed both a precisely the same time then we know that as long as two objects are dropped from the same height then no mtter the weight they will land at the same time.

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.
