Answer:
A linear relationship (or linear association) is a statistical term used to describe a straight-line relationship between two variables. Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b
Step-by-step explanation:
For this case, we convert the mixed numbers into fractions:
![5 \frac {50} {100} = \frac {100 * 5 + 50} {100} = \frac {550} {100} = \frac {55} {10} = 5.5](https://tex.z-dn.net/?f=5%20%5Cfrac%20%7B50%7D%20%7B100%7D%20%3D%20%5Cfrac%20%7B100%20%2A%205%20%2B%2050%7D%20%7B100%7D%20%3D%20%5Cfrac%20%7B550%7D%20%7B100%7D%20%3D%20%5Cfrac%20%7B55%7D%20%7B10%7D%20%3D%205.5)
![2 \frac {72} {100} = \frac {100 * 2 + 72} {100} = \frac {272} {100} = 2.72](https://tex.z-dn.net/?f=2%20%5Cfrac%20%7B72%7D%20%7B100%7D%20%3D%20%5Cfrac%20%7B100%20%2A%202%20%2B%2072%7D%20%7B100%7D%20%3D%20%5Cfrac%20%7B272%7D%20%7B100%7D%20%3D%202.72)
Now, rewriting the expression in three equivalent forms we have:
![\frac {550} {100} - \frac {272} {100} = \frac {278} {100}](https://tex.z-dn.net/?f=%5Cfrac%20%7B550%7D%20%7B100%7D%20-%20%5Cfrac%20%7B272%7D%20%7B100%7D%20%3D%20%5Cfrac%20%7B278%7D%20%7B100%7D)
![5.5-2.72 = 2.78\\2 \frac {78} {100}](https://tex.z-dn.net/?f=5.5-2.72%20%3D%202.78%5C%5C2%20%5Cfrac%20%7B78%7D%20%7B100%7D)
Answer:
![2 \frac {78} {100}](https://tex.z-dn.net/?f=2%20%5Cfrac%20%7B78%7D%20%7B100%7D)
1. A 2.B 3.D 4.C 5.D I cant see the full last one I feel confident about 90% correct I'm just not 100% because its hard to read some
Answer:
Okay, like this...let's assume she travels at a constant rate...
Notice that after three hours, she is 400 miles from home, but after TWO hours more she is only 280 miles from home. That tells us that she travels at 120/2 = 60 miles per hour.
So THAT tells us that her friend's house was 3(60) = 180 miles plus the 400, or 580, miles from her house.
Now we have all we need...we write
d(x) = 580 - 60x
