1/10. EXPLANATION: if you take 2/5 and change it to the equivalent fraction 4/10. you can easily find 1/4 of that. 1/10 is your answer. HAVE A NICE DAY!
<span>Data:
Fee Cars
20 15
30 10
Given that you have only two set of data, you can only assume a linear model.
To find the linear model (equation) that predict the number of cars (x) as a functionn of the parking fee (f) you follow, using only two set of data, follow this procedure:
1) Find the slope, m
m = [10 - 15] / [30 - 20] = - 5 / 10 = - 0.5
2) Use the slope-point equation
y - y1 = m (x - x1)
=> y - 10 = - 0.5 (x - 30)
=> y - 10 = - 0.5x + 15
=> y = - 0.5x + 15 + 10
=> y = - 0.5x + 25
or c = - 0.5 f + 25 <-------- equation
Now you can replace 6 for f to get the number of cars when the fee is $6
c = - 0.5 (6) + 25 = - 3 + 25 = 22 <---- this is the number of cars when fee is $6
Answers:
c = - 0.5 f + 25
number of cars = 22

Answer:
the answer is c
Step-by-step explanation:
i just finished the question
Answer:
Step-by-step explanation:
Hello:
the equation is : y = ax+b
the slope is a : a =2/3 ( same slope parrallal to the line : 2/3x+1=2 )
the line that passes through (-4, 0) : 0 = (2/3)(-4)+b
b = 8/3
the equation is : y = (2/3)x+8/3
