Send the exact assignment or rubric from your classroom and a custom sample written to it lands in 24 to 48 hours, the first one free. MA 109 is Herzing’s College Algebra course. It centers on college algebra, where credit follows the method rather than the final number and extraneous solutions have to be caught. Searches like "ma 109 unit 4 assignment example", "MA109 sample paper", and "MA 109 unit samples" land on this page.
What MA 109 is really about
Almost every mark in this course sits in the working, because an unsupported answer cannot be partially credited and a correct one cannot be distinguished from a guess. MA 109 assignments therefore expect each step written out, with the operation applied to both sides visible, and they expect the result substituted back where the equation type produces extraneous solutions. Radical, rational and absolute value equations all generate candidates that fail the original, and papers that solve correctly and skip the check lose the marks the check was worth. An unsupported answer forfeits the partial credit the method would have earned.
The second demand is domain and interpretation. Denominators that cannot be zero, radicands that cannot be negative and logarithm arguments that must be positive all constrain what counts as a solution, and stating those restrictions before solving prevents most errors rather than catching them afterwards. Word problems are graded on the setup as much as the arithmetic, since defining the variable and writing the relationship is where the mathematics actually happens. Graphing work wants intercepts, asymptotes and behavior labeled rather than a curve with no annotation. Stating restrictions before solving prevents errors rather than catching them later. Word problems are graded on the setup, since defining the variable is where the mathematics happens.
What MA 109’s assessments ask for
Assignments usually mix routine solving with applications and some graphing. Criteria reward every step shown, restrictions stated, solutions checked and answers expressed in the form the question asked, whether that is exact, simplified, interval notation or a rounded decimal to a stated precision. Word problems want the variable defined in words before any equation appears. Where a graph is required, the criteria expect key features identified and the connection between the algebraic form and the picture made explicit rather than left for the reader to infer. Graphing prompts want intercepts, asymptotes and end behavior labeled rather than a curve drawn. Interval notation is expected where inequalities appear rather than an inequality restated in words.
Where students lose points in MA 109
The reliable loss is an answer with no working, which forfeits partial credit and is indistinguishable from copying. Second is a missing check, which lets an extraneous solution through on exactly the equation types designed to produce them. Third is restrictions unstated, so a value that makes a denominator zero survives into the answer. Fourth is a form mismatch, where the work is right and the answer is decimal when exact was required. Fifth is a word problem solved without defining the variable. Sixth is rounding early, which propagates error through everything after it. Early rounding carries its error into everything computed afterwards. A correct method with a slipped digit scores well; a bare answer does not.

Using a MA 109 sample the right way
The example is worth reading for its layout as much as its mathematics, because how a solution is set out determines whether a marker can follow and credit it. Note where restrictions are stated, which is before solving rather than after, and where the check appears. Required answer forms and rounding conventions vary between sections and both cost marks when missed, so confirm what yours specifies and we write the solutions to that convention. Layout decides whether a marker can follow a solution and credit it. Restrictions belong before the solving rather than after it.
How these samples are written
Every sample on this rail is written the way the custom ones are: the rubric decoded row by row, clinical registers held exactly, formats shipped clean. Herzing revises classrooms; a custom request is always written to the rubric in YOUR course, never from a stale template.
MA 109 questions, answered
Why show working if the answer is right?
Because the working is what is being graded. Most of the credit on a solved problem sits in the method, so a correct final number with nothing above it typically earns a fraction of the marks. It also means a small arithmetic slip costs almost nothing when the approach is visible, and costs everything when it is not.
When do I need to check my solutions?
Always on radical, rational, absolute value and logarithmic equations, because the operations used to solve them can introduce values that fail the original. Substitute each candidate back and state the result. Papers that solve these correctly and omit the check lose marks specifically allocated to it, which is among the easiest deductions to avoid.
How should I round?
As late as possible and to whatever the question specifies. Rounding intermediate values propagates error, so carry full precision through the working and round only the final answer. If no precision is stated, give the exact form, because a decimal where an exact answer was expected is marked wrong even when the arithmetic is sound.
