The temperature fell 16 degrees between noon and 3 pm. at 3 pm the temperature was -3 degrees. write and solve an equation to determine the temperature at noon.

13 degrees or, x-16=-3

Step-by-step explanation:

(x is a variable that is unknown)

x-16=-3

x=13 degrees

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

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.
