Does x divided by absolute value of x cancel out to 1?
no it does not because the absolute value is still present in the equation, and everything in the absolute value part will be positive since it can never be negative. Hence x=-1 the equation would set out as -1/l-1l=-1/+1=-1 So when x is -1 y is negative one. however if you plug in positive one it will equal one, but the absolute value has its own conditions that i mentioned earlier
What are good questions to ask when trying to understand a problem?
Which of the following are good questions to ask when trying to understand a problem? Check all that apply.A. What are the units of the variable? B. Does my guess satisfy the equation? C. How should I present the solution? D. What is the variable? E. Is the variable always positive, negative, or either? F. What is a logical name for the variable? for apex-a, d, e and f
Is 1.320 greater than 1.302?
Yes, 1.320 is greater than 1.302. Thats because even with the decimal, the greater number is decided like usual numbers as long as negative sign is not present.
Integers you use in everyday life?
I presume you're talking in particular about places where we use numbers that may be either positive or negative, and it's really helpful to be able to treat them as the same kind of number, instead of needing a separate rule for each combination of negative and positive numbers. Some examples aren't really integers but positive or negative real numbers. How about temperatures? Conversion between Fahrenheit and Celsius on a sub-freezing day is a good exercise in using negative numbers. Elevations go negative in places like Death Valley and the Dead Sea. Comparing the base-to-peak heights of Mount Everest and Mauna Loa is an exercise in subtracting negative numbers. Latitude and longitude are easier to work with if you take east/north as positive and west/south as negative. The most obviously useful calculation here is in working with time zones - you'll find charts with time zones labeled EST = -5, Eastern Europe = +2, etc. Years are a peculiar case. AD and BC were invented around AD 525, before negative numbers (or zero) were really understood, so there was no year zero. The year after 1 BC was AD 1. If it had been done right, we would have been able to compute the years between 43 BC and 33 AD as 33 - (-43) = 76. But because dates aren't integers, you have to say 33 + 43 - 1 = 75. In other words, when the calendar was devised, people just accepted the need for special cases, but with the invention of integers, we found a better way. By the way, the federal government does not assume that taxpayers understand integers, so the 104 form uses the special-case approach: "If line 64 is LESS than line 59, subtract line 64 from line 59 and write it in line 65. If line 64 is GREATER than line 59, subtract line 59 from line 64 and write it in line 66." (That's the idea anyway, I got my form yesterday but I don't have it in front of me.) I can't think of any everyday cases where we multiply negatives by negatives. But when your students learn about quadratic equations, they will be benefiting again from the no-special-cases property of integers. Early developers of algebra had to present solutions for 6 kinds of quadratic equations: Money can also be used as an integer because when you think about it as its in piggy bank going in and out of it, it makes you think about it.
