In y = ax + b, x is called independent variable and y is called dependent variable. a and b are called constants. y = 2x + 5 with a = 2 and b = 5, y = -3x + 2 with a = -3 and b = 2, and y = 4x + - 1 with a = 4 and b = -1 are other examples of linear equations. Remove the fractions (multiply both sides by the least common multiple). c. Factor 4x^2-9. 4x2 − 9 4 x 2 - 9. Rewrite 4x2 4 x 2 as (2x)2 ( 2 x) 2. (2x)2 − 9 ( 2 x) 2 - 9. Rewrite 9 9 as 32 3 2. (2x)2 − 32 ( 2 x) 2 - 3 2. Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = ( a + b) ( a - b) where a = 2x a = 2 x and b = 3 b = 3.

From £37,360 The 697bhp Jeep Grand Cherokee Trackhawk seems like a real beast on paper but our short blast shows it has some likeable manners by James Attwood 2 November 2017 Follow @@Atters_J What. And finally x2 − 4x − 5 = (x +1)(x −5) The fraction becomes. x2 − 5x x2 − 4x − 5 = x(x − 5) (x +1)(x −5) = x x + 1. So, when x approaches 5, the limit is 5 6. Answer link. pwz4I.
