For this one, plug in your <em>x </em> and <em>y</em> intercepts for the corresponding letters and see which one is true. I always start with the first equation and then see which ones solve it first, that will cut your time down on a test.
Lets start with A. (4,5)
and the first equation y=x+1
5=4+1, which is true so A is a potential answer
B. (2,3)
3=2+1, B is a potential as well
C. (-2,1)
1=-2+1, which is false so C is out
D. (-4,-3)
-3=-4+1, which is true.
To cut down on time, do the same thing with the second equation and your final answer will be A. (4,5)
Answer:
Step-by-step explanation:
Add all them up to get 2500
Then you divide 900 by 2500 to get 0.36
Finally you multiple 0.36 by 100 to get 36%
The answer to the question is no
Answer :
There are two cases in this problem :
1). When the ion is positively charged :
Now, the ion and the substance both are positively charged hence when brought together will repel each other because equal charged particles repel each other.
2). When the ion is negatively charged
Now, the substance is positively charged and the ion is negatively charged so both will attract each other because the particles with opposite charges attract each other.
Answer:
The formula is (base x height x 1/2) OR ([base x height] / 2)
