Answer: 5 + 5w
Step-by-step explanation:
We can use the variable <em>x </em>to describe each additional hour, although the vairable can be substituted for any other vairable.
We know that the main cost for one hour is $5, and that each additional hour will cost $5.
Therefore, the equation to reflect this situation would be 5 + 5w, because the first 5 represents the first hour, and the 5w represents how much each hour costs. If you rent two extra hours, then the cost would end up being 15, because the equation would become: 5 + (5x2) = 15.
The equation is 5 + 5w. Hope this helps, and good luck!
Answer:
The correct answer is the Number line with points marked for seven, eight, nine, ten, eleven, twelve. The eight-point is marked with an open circle pointing right.
Supposing you know about the derivative, notice that
so that when
