Step-by-step explanation:

Step 1: Define Systems

y = -6x - 16

-2x + 4y = -2

Step 2: Solve for x

Substitution

Substitute in y: -2x + 4(-6x - 16) = -2Distribute 4: -2x - 24x - 64 = -2Combine like terms: -26x - 64 = -2[Addition Property of Equality] Add 64 on both sides: -26x = 62[Division Property of Equality] Divide -26 on both sides: x = -31/13

Step 3: Solve for y

Define original equation: y = -6x - 16Substitute in x: y = -6(-31/13) - 16Multiply: y = 186/13 - 16Subtract: y = -22/13

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.
