Translate the given statement into an algebraic inequality or compound inequality: The range of temperature on other planets is different than the temperature here on Earth. For instance, the range of
temperature, t, on the surface of Mars is from 28°C to 140°C.
a. 28 b.28>=t>=140
C.28>=t<=140
d. 28<=t<=140

Icould really use some with this question.

Which graph represents the function g(x) = |x + 4| + 2?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
