Unit 2 Assessment

5x + 3 x < 24 a = bc Select all of the following that could be classified as an expression: 2h + 6 d > ef xyz Which phrase best represents the following: 2n + 10 10 increased by a number The sum of a number squared and 10 10 more than twice a number A number squared plus 10 Which phrase best represents the following: 2x - 8 A number squared less than 8 8 less than twice a number 8 less than a number squared Twice a number less than 8 Which represents the expression shown: the quotient of x and 8 plus 7 8x + 7 x + 78 x - 78 8 + 7x Solve: - 3 = t - 44 t= Solve: 3x + 7= 28 x= Solve: 4h - (-6) = -10 h= Select ALL of the steps needed to solve the equation:add 3 to both sides subtract 3 to both sides multiply by 5 on both sides divide both sides by 5 5a + 3= 18 What is the first operation in solving this equation:3+ 2x= -7 subtract 3 on both sides multiply both sides by 2 divide both sides by 2 add 3 to both sies Solve: 1x - 5 = -83 x = -1 x = -39 x = -9 x = 9 Choose all of the following which are true for 2x < -9 The circle is open The graph is to the left The graph is to the right The circle is closed The graph shown represents the solution set for an inequaltiy: Which inequality has the solution set shown on this graph: -3x > 6 3x > -6 3x > 6 -3x > 6 What is the solution to: c -14 < 16 c < 30 c > 2 c > 30 c < 2 C I Which graph represents the solution to: x > -22 I I Complete the solution set for the inequalities using one of the symbols and one of the numbers from the choices shown. -30 > 6y 180 - 180 -5 5 < > y x = 2 x= -2 x = -5 x = 5 x = -6 x = -5 x = -3 x = 0 Select all that have an answer of 16: x - 4 = 12 4x= 4 4 + x = 20 x = 44 Solve -h - 7 = -3 h= Solve b = -93 b = -27 b = 27 b = 3 b = -3 |
