You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h(x)=−12x+300, where x is the time (in seconds) since you first noticed the hot air balloon.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

answer:

c) the x-coordinate of the center of the circle increases by 3

answer: get a conversion sheet out i dont know the exact measurments

step-by-step explanation: divide the number of feet with the nu,ber of milrs and there your answer
