Answer:
The solution set is (-3, 4).
Step-by-step explanation:
x2 + 4x - 9 = 5x + 3
x^2 + 4x - 5x - 9 - 3 = 0
x^2 -x - 12 = 0
(x - 4)(x + 3) = 0
x = -3, 4.
Answer:
6 units
Step-by-step explanation:
They are on the same y-point and so you just have to count the spaces between them on the x-axis.
In order for you to get the answer you must divide. Find a number the goes into both 9 and 81. You're lucky 81 is a multiple of 9. So we can use 9. So 9/81 divided by 9.
9/9=1
81/9=9
So 9/81=1/9
For this case, the first thing we must do is define variables.
We have then:
x: number of rides
y: total cost
We now write the equations for each park.
For The Thrill amusement park:
y = 5x + 40
For The Splash water park:
y = 3x + 60
Answer:
A system of equations that could be used to determine the solution where the cost per ride of the two amusement parks, and, is the same is:
y = 5x + 40
y = 3x + 60
