Answer: x=9
Step-by-step explanation: rewrite the given equation with y=6, 2x + 3(6)=36
Now simplify 2x +18=36
Subtract 18 from both sides of the equal
2x=18
Now divide both sides by 2 and your answer is x=9
Answer:
0?
Step-by-step explanation:
u - v = <5, 2> - <2, - 3> = <5 - 2, 2 + 3> = <3, 5>
given a vector <u, v> then the magnitude is √ (u² + v² ) and it's angle of direction is
θ = ()
thus the magnitude of <3, 5> = √(3² + 5²) = √34 ≈ 5.83 ( to 2 dec. places )
Θ = () = 59.04° ( to 2 dec. places )
