Answer:
39
Step-by-step explanation:
-133/-7=19+15=39
check:39-15=19
19x(-7)=-133
Step-by-step explanation:
directrix = (1, -1)
focus = (-3, 2)
vertex = (-3, 3)
Decrease in the temperature: 5.4×5=27°C
Final temperature: 12-27=-15°C
So floor that you started is x
go down 8 means -8
end on 16
so
x-8=16
add 8
x=24
started on 24
