Answer:
1. 50 = 5x+15
2. 50 = 3x+20
3. 7
4. 10
5. Skating Rink
Step-by-step explanation:
1. As the maximum amount of money is 50 dollars, you are given that there is a 5 dollar entry *per* person, alongside the 15 room rental fee added on. That is where the equation 5x+15 = 50 comes from
2. The same can be said with the skating rink, with different numbers. 3 *per* person plus the extra 20 room rental fee.
3. 50 = 5x+15 can be solved by subtracting 15 by both sides. This gives us 35=5x and dividing by 5 will give us 7 = x
4. 50 = 3x+20 can be solved by subtracting 20 by both sides. This gives us 30=3x and dividing by 3 will give us 10 = x
5. As 10>7, it's apparent that you can bring more people to the Skating Rink
Answer:
x=-1/5
Step-by-step explanation:
2x2-x-1=0
-4x-x-1=0
-5×-1=0
-5×=1
×=-1/5
Answer: As x increases, the slope of the graph increases.
Since the slope is (change in y)/(change in x), and a negative number over a positive number is negative (and vice versa), we want to figure that out. Therefore, we would want 2 to be bigger than the x value and 8 smaller than the y value, or the other way around. (0,9) fits the description, as well as (5, 6)
