Answer:
The inequality symbol is incorrect because she can spend up to and including $65.
The expression 5. 50b + 7. 5 is correct because $5. 50 per book is 5. 50b and that is added to the shipping fee of $7. 50 to determine the total purchase price.
Explanation:
The inequality should be 5.50b + 7.5 ≤ 65 because she can use less than $65 or all $65 to spend on books.
Also, the shipping fee is for all the books she buys combined, not for each individual book so the left side of the inequality should read 5.50b + 7.5.
Answer:
Inconsistent parallel lines is easiest pick k so the slopes (k) is the same as the first line.
It would be helpful to rewrite y-5x=-1 in y=mx+b where m is slope and b is y-intercept
y=5x-1 and y=kx+3 choose k=5 and you will get parallel lines and since the y intercepts are different they will be different parallel lines and inconsistent.
Now consistent intersecting lines are easy now you know the parallel solution is inconsistent so you can choose k to be what ever you want as long as it isn't 5, to make perpendicular just use -1/5.
Explanation:
If you are expecting to have to drive through mountains, it is important to check if: if there be mudslides or rockfalls.
<h3>What are Rockfalls?</h3>
Rockfall can be described as a natural mass-wasting process whereby, there is a rapid downslope and dislodging movement of individual rock masses from their original position.
Mudslides are also similar to to rockfalls which could be dangerous to humans driving through mountains. It can also damage roads.
Therefore, if you are expecting to have to drive through mountains, it is important to check if: if there be mudslides or rockfalls.
