As given,
Step 1: Pick any three-digit counting number
Lets pick the number 643
Step 2: Reverse the digits of the original number.
So, reverse becomes 346
Now, it says that the difference of these two numbers has a tens digit of 9.
Lets, check:
So, its true that the difference has a tens digit of 9.
Another example:
Lets take 449
So reverse is = 944
Difference =
Here also the tens digit is 9.
So, the condition applies to all 3 digit numbers.
The answer would be x <69
The slope of an equation is the number that comes before x. The slope of the line of 1/2x + 2y = 3 is 1/2. The slope of the line of 7 - 3y = 21.
These types of equations are a little tricker because they are not in slope-intercept form.
I hope I helped!
Answer:
14x+49z+7
Step-by-step explanation:

<span> |6 – v| < 9 can be written as two separate inequalities:
+(6 - v) < 9, or -v < 3, or v > -3: (-3, infinity)
-(6-v) < 9, or -6 + v < 9, or v<15: (-infinity, 15)
These two intervals overlap: (-3,15)</span>
