So to start this question you find the prices of the two types of cups and create a basic formula for them. For the mug it would have a base price of $2.95 and a refill price of $0.50. For the disposable cup it would cost $0.85 a piece.
So for the mug you would take the base price of 2.95 and add it by x amount of refills to find the break even point of the two. So the formula would look like 2.95+0.50x. The other would be 0.85x. Now its just a matter of guess and check to see how many refills it would take for the mug to be cheaper. i hope this helped!
If you use your subtraction right when you use deceleration as for example like 4.5 from 79 well you know it had to slow down so the correct Answer for this would end up as 17 .5 Try the easy way like
79 dived by 4.5 would get you the same answer but don't divide backwards you will get an in correct answer
hope i helped;)
6y = -x - 7
<span>y= 6x - 3 </span>
<span>__________________ </span>
<span>y = x/6 + 7/6 </span>
<span>y= 6x - 3 </span>
<span>Compare the gradients, one is 1/6, one is 6. These are not parallel because they aren't the same, and not perpendicular because they aren't negative reciprocals. Therefore, neither.</span>
