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

1) Because the expression is undefined for x = –2, the value –2 must be excluded from the solution set.

2) Because –2 is not represented on the graph.

What is 300 miles to 210 miles in percent of change
Sergeu [11.5K]

Answer:

The Percent change is -30% (decrease)

In this case we have a negative change (decrease) of -30 percent because the new value is smaller than the old value.

Step-by-step explanation:

Here, To find the percentage change, use this formula

<h3><u>Formula</u>:</h3>

Percent change = New - Old ÷ |Old| × 100%

Percent change = 210 - 300 ÷ |300| × 100%

Percent change = -90/300 × 100%

Percent change = -30% (decrease)

Thus, The Percent change is -30% (decrease)

1x + 3 = -5 )-3
1x = -8
At last you must divide 8 by the number, that is multiplied with x:
1x = -8 ):1
x = -8
