Simplify 9y+2y-5y please answer
Brums [2.3K]

Answer:

9y+2y-5y=6y

Step-by-step explanation:

So we have the expression:

9y+2y-5y

To simplify, simply combine the like terms. Therefore:

9y+2y-5y\\=11y-5y\\=6y

Further notes:

To understand why we can combine like terms in the first place, we just need to use the distributive property. So we have the expression:

9y+2y-5y

Now, factor out a y from the three terms:

=y(9+2-5)

Do all the operations inside the parenthesis:

y(9+2-5)\\=y(11-5)\\=y(6)=6y

And we moved the y back to the front!

This is the same result as before. When combining like terms, this is what we're essentially doing but without doing the distributive property manually. I hope you understand a bit better on how and why we can combine like terms!

What is the y-intercept of the line given by the equation below? Enter your answer as an ordered pair.
allochka39001 [22]
We know that the slope formula is y=mx+b. We also know that b=y-intercept. The y-intercept is the location where the line crosses the y-axis on a coordinate plane.

In the equation y=8/13x+7 we know that 7 is the y-intercept. 7 on a coordinate plane is also known as (0,7) when measured on the y-intercept.

Therefore the y-intercept of that equation is: (0,7)
