To give a simple answer
if you consider the equation to be that of a line.
then if the variables cancel out, then the two lines will have the same slope.
two lines with the same slope fall under two categories. Parallel lines, and lines on top of each other
parallel lines have no solutions since the lines never cross each other
lines on top of each other have infinitely many solutions since they "cross" everywhere on the line
It would obviously be about if i had to say proll 50
Answer:
1.98 × 10^10
Step-by-step explanation:
First solve for how many text messages were sent out per one month:
22,000,000 × 900
19,800,000,000
Convert into scientific notation:
1.98 × 10^10
In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.
Answer and Step-by-step explanation:
Try putting a bracket ( ] ), so it looks like this:
(-infinity, -5]
this is because the -5 is included and that's where it stops.
