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 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 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 Drag each solution to the correct problem. = = = 1 ? 2t 2 ? t -2 ? |
