(7/12)x^2 = (1/12) - x-multiply entire equation by 12 to get rid of fractions
7x^2 = 1 - 12x
rearrange to have equation equal zero
7x^2 + 12x - 1 = 0
use the quadratic equation to solve for x
x =
(8/x^2-4)-(3/x^2-4)
(6y-7/y+2)-(2y-11/y+2)-1. 5/x^2
2. 4y+4/y or 4(y^2+1)/y-I think you will find that you are eather wrong or have asked the wrong question.(8/(x^2-4))-(3/(x^2-4… would be a differen
3.0x10^11 = (2x)^2 / (0.0014-x)(4.4x10^-4 -3x)^3-the answer is 2.8x10^-4, I think so anyway, I find knowing the answer helps because then you know if youre getting it right.-Well, the number of the le
Thank You-(x-4) (x-3)The numbers must add to equal the middle # and multiply to equal the last#-factors of 12 are 1, 2, 3, 4, 6, 12
which two factors when u add do u get 7 and their product 12? its 3
A)y=1/4(x+1)^2-2
B)y=1/4(x-1)^2-2
C)y=1/4(x+1)^2+2
D)y=1/4(x-1)^2+2
Please help thank you quick!-Start out by solving x = 2t + 1 for t to get:
x = 2t + 1 ==> t = (x - 1)/2.
Substituting this into y
This is something to do with math...-It is when you simplify a number to where it cant be divided anymore without being even. example: 2*3=6
some prime factors are 2,3,5,7,11,13,17
2 is the only even
The difference quotient is:
[ f (x+h) - (f-x) ] / h
the 1st function is as follows: f(x) = x^2 - 3x The answer is: 2x-3
This one was hard because of all the xs in the function, so I didnt know what
The width of a rectangle is (2x − 4)
in. The length of the rectangle is three times the width. Find the area of the rectangle in terms of the variable x.
3(2x-4) did i set it up right?-yep...
the widt
a) represent f(t) = sin2t, 2π
b) find the laplance transform of cos^2 t-[a].f(t) = | sin2t,2π | 0,otherwise
f(t) = sin2t [u ( t - 2π ) - u ( t - 4π)]
L f(t) = L sin2t . u ( t - 2π ) - L sin2t . u (
i have the equation
(x+2y) * y = y
do i use a linear substitution or homogeneous substitution?-(x + 2y) y = y
divide by x
(1 + 2y/x) y = y/x
let y/x = v
y = vx
y = v + xv
(1 + 2v)(v + xv )
f(x) = 21 2(x+cosx)(1-sinx)
f(x) = 42(x+cosx)(1-sinx)
Chain rule: f(g(x)) = f(g(x))g(x)
Steps:
Ignore the 21 Since all constants remain when taking the derivative of constant x another function.

For a u substitution problem where I take the integral of x/(x+1)^0.5, I get the integral to be 2/3(x+1)^0.5 -2(x+1)^1/2+C.
the textbook though says the simplified answer is 2/3(x+1)^0.5*(x-2)+C.
