these are rational expressions and I need to find the domain written in a set of notations and have a excluded value set and factor
Alpine's street sweeper cleans downtown in 60 hrs. A newer model cleans in 20 hrs. Together, how long to sweep the streets?
(4/x+1)+(1/x^2-x+1)-(12/x^3+1)
__9x+1__ _ __6x-2__ X+1. X+1
2/x + 2/3=1 first i have to get a common denominator,yes? which would be 3x...so its 6/3x+2x/3x=1now i am lost
x²–36 3x 7w-2 16w2-1
Hi, i have 2 application questions about rational inequalities that i hope you will help me solve and explain to me how are they solved: 1)When successful new software is first introduced,...
This question comes from ch.7.3 titled :Adding and subtracting rational Expressions with the same denominator and least common denominator.
I'be tried this problem several times and keep getting stuck. I don't think I'm starting it right.
I've multiplied it out so that they both have a common denominator of (x+4)(x-2) and now I'm confused on what to do next.
Rationalize the denominator in the expression -√2d t = ---- ...
need to find the domain for both expressions g^2 - 6g-55 divided by g k^3 + k divided by K^2 + k - 42
Simplify this rational expression x^2+3x-7 x^2+5x-9 x^2-6x+14 ----------- - ------------- + --------------- x^2-2x-8...
I need help with adding and subtracting rational expressions
For example, if you had: x-3 ------ 5x+3 you'd only find the domain and use the denominator. Why wouldn't you also do the numerator? And...
determine value of k when g(x)= 4x+k does not intersect the parabola f(x)=-3x2-x+4
Simplify the rational expression (Show All work) x^2-8x-48/x+4
I have a few questions on my pre - test study guide that is due tomorrow that I don't understand how to do. I am in math 120 or in algebra 2 for high school - but i am a college student. I have...
The problem is (2x+1/3)-(x-5/4)=1/2
