Currently there are 691,255 trees in a national forest. A park ranger discovered that an untreatable disease is killing the trees at a rate of 1.5% every year.
Lett represent the number of years after the current date. Determine the inequality that can be used to model when there
will be no more than 621,859 trees, and then solve the inequality for t.

691,255(0.985)^t _< 621859; t_> 7

Step-by-step explanation:

C. i just did it

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.
