Thats for questions 3 - 8 that you didn't answer. I'm not quite sure how to answer the last two though.
Answer:
the slope (or rise over run) is 2/3x, and the y intercept is -2
Step-by-step explanation:
In order to find the slope:
- subtract 2x from itself, cancelling it out. Do the same to the other side (-6).
- it should then look like this: 3y=-2x+-6
- next divide 3 from y as well as from -2 and -6.
- it should then look like this: y=2/3x+-2
Answer:
Yes
Step-by-step explanation:
Yes they are because if you divide 18 by 3 you get six and if you divide 15 by 3 you get 5, so it simplifies to 6:3 which is the same as the ratio for rings
88= 44*2
44= 22*2
22= 11*2
neither 11 or 2 have any other prime factors
Answer:
n + 45
Step-by-step explanation:
The question is asking to write an algebraic expression for the sum of a number and 45. We know we are adding a number to 45. So we use addition. But, we don't which number we are adding to 45. So we just use a variable. I used "n", but use whatever letter you want ( x, y, z, etc). I recomend using the same variable that your intrcuctor uses.
Hope this helps.
