... Many people think that this must be all there is, but consider x2 = 2. Contrary to popular belief, there is no fraction (ie no decimal) which when squared equals 2. The solution is x = +√2 or –√2. Most people get out their calculator and say √2 = 1.414… This is simply not true! √2 is only approximat ...

... miles you drive the car each month is linear. The cost is $366 per month for 300 km per month and $510 per month for 1500 km per month a) What linear equation, in standard form, describes the relationship the cost per month and the number of kilometers driven per month? Independent variable (x) = km ...

... 2 Let K be any field, K(t) the field of rational expressiotlSin t over K. This notation would appear to be ambiguous, In that K(t) also denotes the subfield generated by K u ,{t}. But this subfield, since it is closed under the field operations, must contain all rational expressions in t; hence it i ...

... 2x + y = 0 and y = –2x + 1 Write each equation in slope-intercept form. First equation, 2x + y = 0 y = –2x (subtract 2x from both sides) Second equation, y = –2x + 1 (already in slope-intercept form) The two lines are parallel lines (same slope, but different yintercepts), so there are no solutions. ...
