Using the rule y = 8x + 5, find the value of y when x is 6. a) 19 b) 43 c) 50 d) 53

Which quadratic function best fits this data? x y 1 32 2 78 3 178 4 326 5 390 6 337 a. y=11.41x2+154.42x−143.9 b. y=−11.41x2+154.42x−143.9 c. y=11.41x2+154.42x+143.9 d. y=−11.41x2+154.42x+143.9

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.
