The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride, x. The Splash water park charges an entry f
seropon [69]
Answer: The two equations are:
y = 5x + 40
y = 3x + 60

In each problem, you are given the cost per ride. That is the slope, it goes in front of the x. 

Then, you are also given the entry fee. That is the y-intercept, it goes at the end of the equation.

Now, the equations are in slope intercept form. Y = MX + B

Graphing the equations will give an answer of (10, 90)
This means for both plans 10 rides will cost $90.

Answer:

The answer is 600.

Step-by-step explanation:

This is because 5 percent of 800 is 40. 800+40 = 840. 15 percent of 800 is 160. 840 - 160 is 680. 10 percent of 800 is 80. 680 - 80 is 600.

Y= 5x - 9; domain = { 1,3,7 }<br> what is the range values?
Maslowich

Answer:

Step-by-step explanation:

range = [-4,6,26]

Step-by-step explanation:

y = 5x - 9.....domain = [1,3,7]....the domain is ur x values, and I am assuming ur looking for the y values that go with the x ones

y = 5x - 9.....when ur domain (ur x) = 1

y = 5(1) - 9

y = 5 - 9

y = -4

y = 5x - 9...when ur domain (x) = 3

y = 5(3) - 9

y = 15 - 9

y = 6

y = 5x - 9...when ur domain(x) is 7

y = 5(7) - 9

y = 35 - 9

y = 26

so ur range (ur y valus) = [-4,6,26]
