Answer:
It comes down to what the equals sign means. It means, that the two things mentioned on either side of the equation are the same thing. If you do something to the left side, you have presumably changed it.
Step-by-step explanation:
Hope this helps, If it did, then I would really appreciate it if you gave me Brainliest, I only need one more to rank up and it has taken forever to get to where I am currently. Thanks.
Answer:
Any number both positive or negative.
y = {all numbers}
Step-by-step explanation:
Answer:
See Below.
Step-by-step explanation:
Problem 1)
We want to simplify:
First, let's factor the denominators of each term. For the second term, we can use the difference of two squares. Hence:
Now, create a common denominator. To do this, we can multiply the first term by (<em>a</em> + 1) and the second term by (<em>a</em> + 2). Hence:
Add the fractions:
Factor:
Simplify:
We can expand. Therefore:
Problem 2)
We want to simplify:
Again, let's create a common denominator. First, let's factor out a negative from the second term:
Now to create a common denominator, we can multiply the first term by (<em>a</em> - <em>c</em>) and the second term by (<em>a</em> - <em>b</em>). Hence:
Subtract the fractions:
Distribute and simplify:
Cancel. Hence:
Her error was that she thought 0.1 and 1/4 were negatives but they are still positive.
She also thought the larger the negative the greatest one. The smaller negative is the greatest because it's bellow 0.
To solve this you would first need to turn 1/4 into 0.25
It would start out with -2 cause that is the least. Then -1. Now its back to positive so the least to greatest would be normal.
So the real answer would be -2, -1, 0.1, 1/4
