For the tile pattern below, what is a rule that represents the number of tiles in the pattern (y) for the given figure number (x)? Tiles are shaded grey or black. The ones that have been added are black. y = 3x - 3 y = -3x + 3 y = 3x + 3 y = 3x Solve for the value of x in the following equation: If you check your answer in this equation, the final line of the check should read: (fill in the blanks): 4 - 2(3x + 1) = 2x - 6 = Find the slope and y-intercept through the two points: (-6, 0) and (3, 3). If the slope is a fraction, use the / key. Example: 2/5 y = x put a + or - sign here Which pair of lines has perpendicular slopes? y = 2/3x - 4 y = -3/2x +3 2x + 4y = 8 4x + 2y = 4 y = 3x + 1/3 y = -3x - 3 x + y = 5 x - 2y = -3 Choose the number line that represents the solution to the inequality. A B C 12 + 5x - 7 >2x + 23 0 0 6 6 6 Choose the inequality statement that represents the solution to the absolute value inequality. x < 3 -13 < x < 3 -3 < x < 3 x < -13 or x > 3 To solve the quadratic equation k2 - 10k = 20 by completing the square, the first step you would take is: subtract 20 on both sides factor out the common factor, k add 25 to both sides find a, b, and c Factor completely: 12m2 – 4m 4m (3m-1) 12m (m - 4) 4m (3m) (4m + 1)(3m - 1) 2 -2 4 -4 6 -6 2 -2 4 -4 6 -6 8 -8 10 -10 The vertex of the graph is not visible. If the equation is y = x2 + 4x - 5, what is the correct vertex? (-5, 1) (-2, -9) (-2, -8) (0, -5) 2 -2 4 -4 6 -6 2 -2 4 -4 6 -6 8 -8 10 -10 Which inequality corresponds to the graph? 2x - 3y > -9 2x + 3y > -9 2x + 3y < -9 2x - 3y < -9 2 -2 4 -4 6 -6 2 -2 4 -4 6 -6 8 -8 10 -10 Drag each term belowto its correct position. Then choose the equation that goes with the graph y = x2 + 6x + 5 y = x2 - 6x + 5 y = x2 - 4x - 5 y = x2 + 4x + 5 y-intercept (0,5) ? root: (1,0) ? Vertex ? root: (5, 0) ? The first step to solving this system of equationsusing the Elimination Method could be: 1) 2x + y = -7 2) 3x - 2y = 0 Multiply equation 1 by -1 Add the two equations together Multiply equation 1 by 2 Subtract the two equations Click on the region that should be shaded to show the solution to the system of inequalities: C B D y > 2x - 1 y > - x +1 A 1 3 How many solutions does each equation have?Drag the correct number of solutions next to eachequation. has 0 solutions ? has 1 solution ? has 2 solutions ? x(x + 7)(x - 2) (x - 7)2 x (x + 2)(x - 1)2 Divide. Choose the correct, simplified solution. (x — 7) x(x + 2) x(x + 2) 1 Drag each solution to the correct problem. = = = 1 ? 2t 2 ? t -2 ? |
