Aconstruction crew is digging a hole. on the first day, they dug a hole 3 feet deep. on the second day, they dug 2 more feet. on the third day, they dug 4 more feet. write a sum of negative numbers to represent this situation. find the total sum and explain how it is related to the problem.

It would be dug 9 feet deep hole in the ground.

Step-by-step explanation:

Since we have given that

On the first day , they dug a hole of length = 3 feet

On the second day, they dug a hole of length = 2 feet

On the third day , they dug a hole of length = 4 feet

Since all the above integers are negative integers as they are length beneath the ground.

So, Sum of negative numbers would be

And the total sum would be

Hence, it would be dug 9 feet deep hole in the ground.

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.
