How to do I do solving systems of equations by elimination

Mathematics
1 answer:
Andre45 [30]4 years ago

If you have two equations, you will multiply one of them so it cancels out the other one. For Example, 2x-y=16        3x-y=28You will multiply the second equation by -1 which brings us to 2x-y=16    -3x+y=-28you will add both equations together which will leave you with-x=-12x=12Then, you plug that in. 2x12=24.    24-16=8.    3x12=36     36-8=28    And, You're done!

I NEED HELP PLEASE, THANKS! :) A commercial passenger jet is flying with an airspeed of 185 miles per hour on a heading of 036°.
Sindrei [870]

We are given that the passenger's jet is flying at a speed of 185 miles per hour, with a direction of 36 degrees, and the wind speed being 47 mph with a direction of 120 degrees. From this, you could create a diagram is shown in the attachment.

[ 185 cos 36, 185 sin 36 ]

+ [ 47 cos 120, 47 sin 120 ]

_______________________

[ 185 cos 36 + 47 cos 120, 185 sin 36 + 47 sin 120 ]

√( 4263  + 33988 )^2

= ( About ) √38251 = 195.57 mph

<u><em>Solution = 195.6 mph, 069° </em></u>

Nearest Integer of the square root of -61?
OLga [1]
You cannot take the square root of a negative number and get a real number answer. You can only get an imaginary root.

square root of 49 = 7 and square root of 64 = 8
square root of 61 is between 7 and 8.
It would be closer to 8.

square root of -49 = 7i and square root of -64 = 8i
square root of -61 would be closer to 8i
