If this pattern continues, what is the sixth term? −41.6 41.6 83.2 −83.2 Which of these equations describes the relationship between the x-values and the y-values? y = x + 5 y = 5x − 2 y = 2x − 5 y = x + 2 The table below shows a cubic relationship between x and y. If this pattern continues, what is the value of y when x = 7? The width and length, in feet, of a rectangular playground are x and x + 2. A fence costs $17 per foot. Which of these expressions represents the cost, in dollars, to build a fence around this rectangular playground? 17x(x + 2) 17 + x + (x + 2) 17[x + (x + 2)] 17[x + (x + 2) + x + (x + 2)] If this pattern continues, what is the value of y when x is 10? 66 108 89 129 Which of these describes the range of this function? all real numbers all whole numbers 0 ≤ y ≤ 5 y ≥ 0 3, 10, 17, 24, 31, . . .
If the pattern continues, what will be the tenth term? 38 66 62 73 2, 6, 18, 54, ...
If this pattern continues, what is the sixth term? A company spends 2x + 3,000 dollars for materials to make calculators. The cost of labor to make these calculators is 3.2x + 3,500 dollars. Which expression represents the difference between the cost of labor and the cost of materials? (3.2x + 3,500) + (2x + 3,000) (3.2x + 3,500) − (2x + 3,000) (3.2x + 3,500) × (2x + 3,000) (3.2x + 3,500) ÷ (2x + 3,000); x ≠ − 1,500 Which equation represents this relationship? y = x ³ y = x − 1 y = x 2 y = x + 2 A In a recipe for spice cake, the ratio of flour to milk is 3 to 1. Which of these tables shows the correct amount of flour and milk needed to make more than one spice cake? B |
