Hi there!
So -5 1/2 + 7 3/4 is
Improper fraction: 9/4
Decimal: 2.25
Mixed Number: 2 1/4
The rate of change of a function can be modeled with the following expression:
![\frac{\Delta{k{x)}}{\Delta{x}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%7Bk%7Bx%29%7D%7D%7B%5CDelta%7Bx%7D%7D%20)
Where Δx is the change in x value, and Δk(x) is the corresponding change in k(x). We're given the two extremes of x, so we can calculate the change in x to be
![\Delta{x}=-4-(-14)=10](https://tex.z-dn.net/?f=%5CDelta%7Bx%7D%3D-4-%28-14%29%3D10)
To find the change in k(x), we can calculate the values of k(x) at x = -14 and x = -4 and find the difference between them:
![k(-14)=5(-14)-19=-70-19=-89\\ k(-4)=5(-4)-19=-20-19=-39\\ \Delta{y}=k(-14)-k(-4)=-89-(-39)=-50](https://tex.z-dn.net/?f=k%28-14%29%3D5%28-14%29-19%3D-70-19%3D-89%5C%5C%20k%28-4%29%3D5%28-4%29-19%3D-20-19%3D-39%5C%5C%20%5CDelta%7By%7D%3Dk%28-14%29-k%28-4%29%3D-89-%28-39%29%3D-50)
So, the rate of change for the function from x = -14 to x = -4 is
Answer: 1. ( 9r - 8 ) x ( r - 2 )
2. ( 5b - 3 ) x ( 5b + 3 )
Step-by-step explanation:
Answer:
35/4
Step-by-step explanation:
- 8 × 4 = 32
- 32 + 3 = 35
- Write 35 over the original denominator: 35/4
I hope this helps!
