Let
x-------> the time in minutes
y-------> the temperature in Fahrenheit degrees
![A(2,150)\\B(3,190)](https://tex.z-dn.net/?f=A%282%2C150%29%5C%5CB%283%2C190%29)
we know that
<u>the change in the y-values between two points is equal to</u>
![(y2-y1)](https://tex.z-dn.net/?f=%28y2-y1%29)
Substitute the y-values of the point A and B in the formula
![y2=190\\y1=150](https://tex.z-dn.net/?f=y2%3D190%5C%5Cy1%3D150)
![(190-150)=40](https://tex.z-dn.net/?f=%28190-150%29%3D40)
<u>the change in the x-values between two points is equal to</u>
![(x2-x1)](https://tex.z-dn.net/?f=%28x2-x1%29)
Substitute the x-values of the point A and B in the formula
![x2=3\\x1=2](https://tex.z-dn.net/?f=x2%3D3%5C%5Cx1%3D2)
![(3-2)=1](https://tex.z-dn.net/?f=%283-2%29%3D1)
therefore
<u>the answer is</u>
The change in the y-value is
and the change in the x-value is ![1](https://tex.z-dn.net/?f=1)
Answer:
72 signs
Step-by-step explanation:
90 min = 1.5 hour
6 hours hangs 6/1.5 * 18 signs = 72
Answer:
34, 1.5, 9, 12, 3.6
