1) y=-x+4, the slope is -1
2)y=-x+4, slope is -1
3) yes
4)It's the same line if the slopes and y-intercepts are the same, so the number of corresponding points are infinite.
Answer:
A. 49
Step-by-step explanation:
The average rate of change for the interval ranging from x = 3 to x = 5 for the given function represented in the table above can be calculated using:
![Average rate of change = \frac{f(x2) - f(x1)}{x2 - x1}](https://tex.z-dn.net/?f=%20Average%20rate%20of%20change%20%3D%20%5Cfrac%7Bf%28x2%29%20-%20f%28x1%29%7D%7Bx2%20-%20x1%7D%20)
x2 = 5
x1 = 3
f(x2) = f(5) = 125
f(x1) = f(3) = 27
Thus,
![Average rate of change = \frac{125 - 27}{5 - 3}](https://tex.z-dn.net/?f=%20Average%20rate%20of%20change%20%3D%20%5Cfrac%7B125%20-%2027%7D%7B5%20-%203%7D%20)
![= \frac{98}{2}](https://tex.z-dn.net/?f=%20%3D%20%5Cfrac%7B98%7D%7B2%7D%20)
Average rate of change = 49
Average rate of change of the given table values representing an exponential function is A. 49.
Answer:
9/2
Step-by-step explanation:
m=∆y/∆x
m= (5+4)/(2—0)
m=9/2
I think its c but you might want to check just in case I'm wrong.
