Answer: A
Step-by-step explanation:
The first thing we need to do is to make sure our equation is in standard form. The given equation is not in standard form.
3x²-2x=0
Now that the equation is in standard form, we can find our A, B, C to see which quadratic equation is correct.
A=3
B=-2
C=0
We can automatically eliminate D because the first value is -3 when it is supposed to be -(-2). Also, the denominator is supposed to be 2a. We know that A=3. The denominator should be 2(3), not 2(-2).
Next, we can eliminate B and C. For the 4ac, we know it has to be 4(3)(0) because A=3 and C=0. B and C have given 4(3)(2) and 4(3)(1), respectively. This does not match A=3 and C=0.
Therefore, A is the correct answer.
Answer:
I really hope it will help you....
Step-by-step explanation:
Answer1-we can see that in last two hours the line is downwards so we can easily proof or see that at 11th and 12th are the temperature is lowest.
Answer2-in second one we can see that in hour 1,2,3,4 the temperature has kept on increasing.
Answer 3- between three or four temperature of increasing.
The answer I believe it’s A if not try C
