From the sum of 3x – y + 11 and - y - 11, subtract 3x - y-11.

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.

Find the solution of this system of equations -7x+y=-20 9x-3y=36

An animal shelter has fixed weekly expenses of $750. each animal is the shelter costs an additional $6 a week. during the summer months, the weekly expenses are at least $1170. write and solve an inequality that represents the number of animals at the shelter for expenses to be at least $1170 a week.
