@saifoo.khan Hi can i please get some help...?
3. Having survived the meteor impact, thanks to some last-minute evasive maneuvers, the Mathonauts now set their sights on their Interstellar Headquarters. The Interstellar Headquarters orbits the Earth based on the equation y2 + x2 = 40,000. Using the original trajectory of the ship and complete sentences, explain to the pilot how to find where the ship’s path will cross the Interstellar Headquarters’s path.
Original trajectory is y=2x+1
I have to use Elimination or Substitution
Solve simultaneously?
Use substitution.
could you please show me how...
so if we have y2+x2=40,000 and y=2x+1 so do i do (2x)2+1
y2 + x2 = 40,000 and y = 2x+1. So insert the y of second equation into one. (2x+1)^2 + x^2 = 40000 Like this.
i'm solving it
i got 7.6
4x2+2+x2=40,000 5x2+2=40,00 subtract 2 5x2=38 divide 5x2 x=7.6 Is it right..
@saifoo.khan are you there? did i do it right..
(2x+1)^2 + x^2 = 40000 (4x^2 + 4x + 1) + x^2 = 40000
i don't understand what you did.
FOIL?
so now solve it..
you want me to do it just like in the video
Yes.
