We know that
in the expression 3/(x+2)
for x=-2> the denominator is zero

And the denominator cannot be zero, therefore the value of x = -2 can not belong to the domain of the function. That is the reason why the value of x = -2 cannot be included

Answer from: sandyykn6031

The denominator never be zero because if the denominator is equal to zero then the function or inequality is not defined, that is x $\neq$ -2.

Given :

$\dfrac{3}{x+2}+4\geq 3$

The following steps can be used in order to graph the solution on the number line:

Step 1 - Write the given inequality.

$\dfrac{3}{x+2}+4\geq 3$

Step 2 - Before simplifying the inequality, remember that denominator never be zero because if the denominator is equal to zero then the function or inequality is not defined, that is:

x + 2 $\neq$ 0

x $\neq$ -2

Step 3 - SImplify the given inequality.

$\rm \dfrac{3}{x+2}\geq -1$

Cross multiply in the above inequality.

$\rm 3\geq -1(x+2)$

Further, simplify the above inequality.

$\rm x\geq -5$

Answer from: Quest

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

the most boring ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
