Answer:

Step-by-step explanation:
Before you add 2 fractions, the denominator needs to be the same. If they are the same, which they are, then add the 2 numerators.
1 plus 2 equals 3.
So the answer is 3 over 5.

A cube number is an integer which is a third power of another integer.
A triangular number is a number that counts the objects that can form equilateral triangle (sorry, I cribbed it a little from Wikipedia; it's difficult to explain). Just look at the picture.

So, if you're trying to solve an equation, here's an example:
2x + 4y = 8
You would minus 2x from both sides. (you want to get the equation into a mx + b format)
4y= -2x + 8
you would now divide both sides by 4
y = -1/2x + 2
So now that your equation is in y = mx+b, you should know your answer.
mx= to slope
b= y-intercept
so, therefore, your y-intercept is 2.
