Answer:
it's "-27" :D
Step-by-step explanation:
....................
The ? Is 11.
You add the equations to get rid of one variable, then you have 6x=24 then you divide both sides and you have x=4, then you substitute the given value of x and you are left with 5*4 - y = 9. And the solution or well possible solution is y = 11 which gives youuuuu. (x , y) = (4 , 11)
Answer:
see explanation
Step-by-step explanation:
To find the zeros equate g(x) to zero, that is
(x - 2)(3x + 3) = 0
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
3x + 3 = 0 ( subtract 3 from both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1
Hence
smaller x = - 1
larger x = 2
2*2+3x+8=0
4+3x+8=0
12+3x=0
3x=-12
x=-4
<span>∫c F · dr
= ∫∫s curl F · dS, by Stokes' Theorem
= ∫∫ <2, 0, -x> · <-z_x, -z_y, 1> dA
= ∫∫ <2, 0, -x> · <1, 0, 1> dA, since z = 2 - x
= ∫∫ (2 - x) dA.
Since the region of integration is inside x^2 + y^2 = 9, convert to polar coordinates:
∫(r = 0 to 3) ∫(θ = 0 to 2π) (2 - r cos θ) * (r dθ dr)
= ∫(r = 0 to 3) (2 * 2π - 0) * r dr
= 2πr^2 {for r = 0 to 3}
= 18π.
