Answer:
No, because a x-value repeats.
Step-by-step explanation:
A function has x-values that correspond to exactly one y-value. In the given table, <u>the number '5' appears twice as an x-value</u>. This means that the relation is not a function, "because one x-value corresponds to two different y-values."
Given:
Charlie bought a new computer for $450 with his credit card.
He plans to pay the minimum payment of $25 per month.
To find:
The rate of change.
Solution:
Let y be the remaining amount of loan after x months.
Initial amount of loan = $450
Payment of one month = $25
Payment of x months = $25x
Now,
Remining amount = Initial amount of loan - Payment of x months
...(i)
The slope intercept form is
...(ii)
where, m is slope and b is y-intercept.
From (i) and (ii), we get
![m=-25](https://tex.z-dn.net/?f=m%3D-25)
Therefore, the rate of change is -25 dollars.
Answer:
Im in 7th grade and I need some help on a math problem. can I post it?
Answer:
![h(x) = 10](https://tex.z-dn.net/?f=h%28x%29%20%3D%2010)
Step-by-step explanation:
Given
![h(x) = |2x| - 4](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%7C2x%7C%20-%204)
![x = -7](https://tex.z-dn.net/?f=x%20%3D%20-7)
Find h(x)
Substitute -7 for x
![h(x) = |2*-7| - 4](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%7C2%2A-7%7C%20-%204)
![h(x) = |-14| - 4](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%7C-14%7C%20-%204)
Absolute values return positive. So:
![h(x) = 14 - 4](https://tex.z-dn.net/?f=h%28x%29%20%3D%2014%20-%204)
![h(x) = 10](https://tex.z-dn.net/?f=h%28x%29%20%3D%2010)
