Why does the equation 9−2x−9−16x=−14x−7−4x−11 have no solutions? A) because if you add 18x to both sides of the equation and simplify, you get −18=−18

B) because if you add 18 x to both sides of the equation and simplify, you get 0 = - 18

C) because if you subtract 18x from both sides of the equation and simplify, you get −18=−18

D) because if you subtract 18x from both sides of the equation and simplify, you get 0=−18

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
