So when one goes up, the other goes down. This is an inverse equation.
An inverse equation looks like this: y = 1/x
In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300
So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00
6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
Answer:
The answers are as follows: 12 106 42
Step-by-step explanation:
Given: 
Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate 
separately and 
separately and add them. So we have 
.
Now for the second question: 
. we would get 
Next, 
. This could be written as: 
. Hence the answers.
Answer:
Yes number 5 is, they are proportional because y is coresponding to x by multiplying by 1/5
No number 6 isn't, you can't go from 3 to 1 and 7 to 3
<u>Answer:</u>
A red marble out of the same jar, without replacing the first marble.
<u>Step-by-step explanation:</u>
Dependent events are those which involve a first event which affects the outcome of the second event.
This means that the probability of the second event changes because of the occurrence of the first event.
So if a blue marble is drawn out of one jar, then drawing a red marble out of the same jar, without replacing the first marble would be an example of dependent events.
The slope is a 2
here the stpes
6/3 got 2
y2-ya
x2-x1
then you get 6/3 devide ad that you slope
