Answer:
i think u should first givr her discount by doing 20/100×3500=700 and than he will get 5 percent profit than here
3500-700=2800
now for 5 % profit
5/100*2800=140
hence
20% discount=700
5% profit =140
it might be wrong but here u go
5. Center (-2,3) Radius 3
6. Center (-2,0) Radius √11
7. Center (0,-4) Radius 5
8. Center (3/2,-4) Radius 3√17/2
9. Center (6,8) Radius 4
10. Center (-1,-2) Radius 4
Ive attached what the graphs will look like, I cannot add the last graph since its the image limit for this website.
Hope this helps, feel free to PM me if you are still having trouble and need the last graph :)
Answer:
Step-by-step explanation:
1) the two members of the expression has 4x in common, so we can rewrite it as: 4x(3x-2)
2) we have to find two numbers that multipied give -36 and that added up give 5
the two number are 9 and -4
we can rewrite the expression as : (x+9)(x-4)
3) we have to solve the associated equation
3x^2+10x+8 = 0
Δ/4 = 25-24 = 1
x1 = (-5+1)/3 = -4/3
x2 = (-5-1)/3 = -2
now we can rewrite the expression as
3(x+4/3)(x+2) = (3x+4)(x+2)
