Pick two of the following statements and determine if the statement makes sense or not, and explain your reasoning (see rubric) 1. The rules for the order of operations avoid the confusion of obtaining different results when I simplify the same expression.
2. I saved money by buying a computer for 3/2 of its original price.
3. I find it easier to multiply 1/5 and ¾ than add them.
4. I rationalized a numerical denominator and the simplified denominator still contained an irrational number.
5. The irrational number Pi is equal to 22/7.
Pick two of the following statements and determine if the statement makes sense or not, and explain your reasoning (see rubric)
1. My body temperature is a function of the time of the day.
2. A linear function that models tuition and fees at public four-year colleges from 2000 to 2010 has a negative slope.
3. Because the variable m does not appear in Ax + By = C, equations in this form make it impossible to determine the line's slope.
4. When graphing a linear inequality, I should always use (0,0) as a test point because it's easy to perform the calculations when 0 is substituted for each variable.
5. Systems of linear inequalities are appropriate for modeling healthy weight because guidelines give healthy weight ranges, rather than specific weights, for various heights.
