The answer is Motivational
let X be number of students
and y be total cost
when 30 students (30,X)where at the gym it's costs 200 (y,200)
=that is (X,y)=(30,200)
when 70 students where at the gym
=(X,y)= (70,330)
now we find the slope
M=y2-y1/x2-x1
= 330-200/70-30
= 100/40
= 2.5=3
now
Y=Mx+b
Y=2x+b
we need to find the value of b
so,we substrate for X and Y
X=30,200
200=2(30)+b
re-arrange
B+60=200
B=200-60
=140
y=2x+140
For the other questions, I can look at the equation I got. The y-intercept (b value) is $200. That means that we are adding $200 on to the price all the time. That's the price for the empty bus. The 2x means to multiply the number of people by two and add this to the $120. So each person is $2.
hope it's helpful
and please I really need brainliest, thanks
2x^2 - 5x + 1 = 3
Subtract 3 from both sides
2x^2 - 5x + 1 - 3 = 3 - 3
2x^2 - 5x - 2 = 0
Use quadratic formula with A = 2, B = - 5, C = - 2
x = - b +- sqrt b^2 - 4ac/2a
x = - ( - 5) +- sqrt (- 5)^2 - 4(2)( - 2)/(2)(2)
x = 5 +- sqrt 41/4
x = 5/4 + 1/4sqrt 41 or x = 5/4 + - 1/4 sqrt 41
Answer: x = 5/4 + 1/4 sqrt 41
x = 5/4 + - 1/4 sqrt 41
Hope that helps!!!!! (D)
Answer:
![\[\frac{3}{4}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B3%7D%7B4%7D%5C%5D)
miles
Step-by-step explanation:
The relay team consists of 4 people.
Total distance covered by 4 people = 3 miles
Each person runs the same distance.
This means that each person will run a distance equal to:
![\[\frac{distance}{persons}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7Bdistance%7D%7Bpersons%7D%5C%5D)
![\[=\frac{3}{4}\]](https://tex.z-dn.net/?f=%5C%5B%3D%5Cfrac%7B3%7D%7B4%7D%5C%5D)
So each person in the relay team of 4 will run a distance of miles to cover the entire length of 3 miles.
