In the earlier section we solved equations which contained absolute values. In this section we desire to look at inequalities which contain absolute values. We will have to examine two separate cases.
Inequalities Involving < and ≤
As we did with equations let's begin by looking at a fairly simple case.
p ≤ 4
This says that no matter what p is it ought to have a distance of no more than 4 from the origin. It means that p have to be somewhere in the range,
-4 ≤ p ≤ 4
We could have alike inequality with the < and obtain a similar result.
Generally we have the following formulas to use here,
If |p| ≤ b, b = 0 then - b ≤ p ≤ b
If |p| < b, b =0 then - b < p < b
The sum of digits of a number is 9 If the digits of the number are reversed the number increases by 45 What is the original number?
Fact Following any system of equations there are accurately three possibilities for the solution. 1. There will not be a solution. 2. There will be just one solution.
In this section we will see how knowledge of some rather simple graphs can help us graph some more complexes graphs. Collectively the methods we will learn in this section are cal
I need help with my Discussion 1 for week 5 please. w^2 + 30w + 81 and ac + xc + aw^2 + xw^2 and last one is x^4 - x^3
x^2+6x+8=0
9x^4-x^2=0 step by step
(-11,-3),(0,-7)
6[5b+9]=2b+9.
Distance/Rate Problems These are some standard problems which most people think about while they think about Algebra word problems. The standard formula which we will be using
(x^3+2x^2-4x-8)/(x^4-16)x(3x^2+8x+5)/3x^2+11x+10)
