I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.
LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is
x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10
Subst. 10 for x in the original equation to verify that 10 is indeed a solution.
Answer:

Step-by-step explanation:
Lol I use the calculator and find the cost of 30 of 85.40 than the number of the percent is 25.62 so I subtract them both and got 59.78 as an answer hope this help
Answer:
m is the slope of line and x1, y1= 2,5 , and x2, y2= -4, 5
m = 5-2/-4-5 = -1/3

Step-by-step explanation:
If 2 functions are inverses then the x and y- coordinates swap, that is
(x , y ) → (y, x )
Thus
a = - 3.8 ← the x- coordinate of the inverse
b = - 2.6 ← the y- coordinate of the inverse
c = 1.7 ← the x- coordinate of the inverse
d = 4.4 ← the y- coordinate of the inverse
e = 1.0 ← the x- coordinate of the inverse
