Quiz Math 70 Answer Key Revealed: Full Step-by-Step Solutions and Proof
By James H. Sterling
Q1: Why is 70% considered the universal passing baseline in Math 70?
A1: Under US collegiate and secondary accreditation guidelines, a 70% (grade of C) demonstrates foundational competency. Because intermediate algebra serves as the direct prerequisite for pre-calculus, statistics, and chemistry, scores below 70% correlate with high failure rates in subsequent STEM coursework.
Q2: Can I use a graphing calculator on the Math 70 quiz?
A2: Most collegiate mathematics departments restrict or outright ban graphing calculators (such as the TI-84 or TI-Nspire) during the algebraic foundations unit. Students are typically restricted to basic scientific calculators (like the TI-30XIIS) to ensure they can execute factoring, polynomial long division, and radical simplifications by hand.
Q3: What happens if I solve a radical equation correctly but forget to check for extraneous solutions?
A3: Leaving an extraneous root on your final answer sheet will cost you substantial points. Most departmental rubrics deduct 50% of the question's total value if invalid roots are not identified and discarded.
