This is easier than you think!
When a graph shows direct variation, it always <em>passes through the origin</em>
The origin is (0, 0)
The very <u>center! </u>
Your answer is the first graph!
Fractions need common denominator to add or subtract them because without denominators a fraction is not a fraction, it is a whole number
Example - 2/8 is a fraction
but 2 is not a fraction
Answer:
3
Step-by-step explanation:
It's simply changing the order.
In the first number, 2 is in the thousand's place, it means two thousand.
in the second number, 2 is in the hundred's place. It means two hundred.
First, you need to get delta which is b squared minus 4ac. If delta is higher than cero, the polynomial has two solutions, if it is less, the polynomial has no real solutions and if it is the same, it has one solution.
Although that is only for second grade ecuations
