The product of the expression (\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1}  is the expression \frac{2}{k+2}

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the expression:

(\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1} \\\\This\ can\ be\ simplified\ to:\\\\(\frac{2(2k+1)(k-2)}{(k+2)(k-2)(2k+1)}) \\\\=\frac{2}{k+2}

The product of the expression (\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1} is the expression \frac{2}{k+2}

The difference of two numbers is 30. their quotient is 6. what are the two numbers
BlackZzzverrR [31]
Well, the quotient must be bigger/smaller

lets say the numbers are x and y
x>y

so
x-y=30 and x/y=6
multiply both sides by y in 2nd equation
x=6y
subsitute 6y for x in other equation

6y-y=30
5y=30
divide by 5
y=6

sub back
x=6y
x=6(6)
x=36


the numbers are 36 and 6

but they could also be -36 and -6 because -36/-6=6 and -6-(-36)=30


the 2 numbers are 36 and 6 or -36 and -6

How do I solve this inequality?
djverab [1.8K]

Step-by-step explanation:

9 ≤ |4x + 7|

9 ≤ 4x + 7

9 - 7 ≤ 4x

2 ≤ 4x

2/4 ≤ x

<h2>1/2 ≤ x</h2>

9 ≤ |4x + 7|

9 ≤ -(4x + 7)

9 ≤ -4x - 7

9 + 7 ≤ -4x

16 ≤ - 4x

16/-4 ≤ x

<h2>-4 ≤ x </h2>

<h2>{-4 ≤ x ≤ 1/2} </h2>
