The soldering iron’s highest temperature setting is 400 °F. What is the soldering iron’s temperature in Centigrade?

204.4(repeating) degrees

Step-by-step explanation:

The equation to go from F to C, is (F-32)×5/9. So 400-32 is 368.

368×5=1840

Than 1840/9=204.44 degrees. The 4 is repeating at the end.

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.
