T is greater than -15 because numbers after -15, like -16... are less than -15, so when its decreasing it gets lower. Since the questions says the temp stayed above -15, that means the temp could be -14...-13 and so on.
Middle option.
<span>(x + 1 ≤ 1) ∩ (x + 1 ≥ 1)
If you work both sides separately you get
</span>(x ≤ 0) ∩ (x ≥ 0)
<span>
which reduces nicely to
</span><span>{x | x = 0}</span>
U would multiply the number on the side and the number on the bottom. hope that helps :)
Cut in half long ways and short ways straight down the middle
the a line from opposite corners each way
then a slanted line the hits the center would also create two congruent figures
Answer: Its hard to explain, so I'll just give you the answer (47 degrees)
