Answer:180
Step-by-step explanation:
Answer:

Step-by-step explanation:
So we have the expression:

To simplify, simply combine the like terms. Therefore:

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:

Now, factor out a y from the three terms:

Do all the operations inside the parenthesis:

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!
Answer:
1/5
Step-by-step explanation:
Use Pythagoras theorem
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)
