Paula is located at a position of −12 feet relative to the ground. Which statement shows the distance she is from ground level? A. |12| = −12, therefore Paula is at a distance of −12 feet B. |−12| = 12, therefore Paula is at a distance of −12 feet C. |−12| = 12, therefore Paula is at a distance of 12 feet D. |12| = 12, therefore Paula is at a distance of 12 feet

(9x-5) - (x+12) what’s the answer and also explain how to do it i need it for a test tomorrow

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?

Write a description of each inequality. 1. -5a + 3 > 1 2. 27 - 2b < -6 (this < has a _ under it) 3. 1/2 (c + 1) > 5 (this > has a _ under it)
