Determine the average rate of change from t = 2 to 4
Average rate of change is :
In this case: a = 2 and b = 4
So, we have:
Assume that the exponential function is:
f(4) and f(2) will be:
So:
Take LCM
<em>So, the average rate of change is a decrease of 4/81</em>
Answer:
x=3 y=2
Step-by-step explanation:
Step one:
Add both equation
2x+3y=12
+ 15x-3y=39
___________
17x=51
x=3
Step 2: After finding the answer for x, plug it into the first equation to find the value of y
2(3)+3y=12
6+3y=12
3y=6
y=2
