2x+y=a
3x+6y=b-Solve the first to get
y=a-2x
Substitue into the second to get
3x+6(a-2x)=b
Solve for x
3x+6a-12x=b
x=-(b-6a)/9
Substitute into the first
2(-(b-6a)/9)+y=b
Solve for y
y=2(b-6a)/9
If f , g, and h are differentiable functions such that:
f (0) = 1, g(0) = 2, h(0) = 3, (gh)′ (0) = 4, (hf )′ (0) = 5, and (f g)′ (0) = 6
find the value of (f gh)′ (0).-(fg) = fg +gf = 2f + g = 6

three pigs brought back 7 mushrooms arrange the mushrooms in the baskets so any total of mushrooms from 1-7 can be made. u cannot remove any mushrooms from baskets to help make up the totals for this
just tell me if for r^2 it is {n(n-1)(2n-1)}/6 then what would it be for r^3 because i need to solve for x^3.-n
Σ . ( r² ) = n(n+1)(2n+1) / 6
r=1
_________________________
n
Σ . ( r³ ) = n² (n+1)² /
Do I take √16 and √4? ... If thats right, from there I dont want what to do.-If you want to find the square root of 64, it is 8. But if you want the result to be 8i you must find the square root of -6

how to simplify 28/91 Please help!!!!!?
7 * 4 = 28
7 * 13 = 91
you could try !
28/91 = 4/13
qed-find a factor of 28 and 91.
for example:
45/415 Divided by 5 = 8/83-28 and 91 both go into 7 so whe
you have to rewrite this equation: 2(y^2)-x-4y+5=0
at first i thought it could be rewritten into a parabola or hyperbola but now i dont know. thanks for the help!-2y² - x - 4y + 5 = 0
There is a only
do i simplify tan^3 5x to tan(tan^2 5x) as the first step?-lim x---0 (tan^3 5x/125x^3)*(4x/sin4x)*(125x/4x)
=lim x---0 125/4since lim x---0 tan x/x = x/sin x = 1
what you were thinking was wrong .It
y-x^2=4x-3
y+2x^2-4x-1
PLEASE HELP!!-For your problem, I assumed equation two was y+2x^2 = 4x-1. If its something different, the steps should be very similar.
