A plane flying horizontally at an altitude of miles and a speed of 580 mth passes directly over a radar station in the rate at which the distance from the plane to the station is increasing when it is 5 miles away from the station (Round your answer to the nearest whole number.)

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

-6 is the correct option from the above given options

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
