X-1=-2x+5
X=2
Y=-2(2) + 5
Y= 1
Answer:
1/2
Step-by-step explanation:
sin = opposite/hypotenuse, so
sin(B) =
= 1/2
X=1
Subtract four so you get 1/x=1
Multiply by x
1x=1
Divide by 1
Answer:

where x₁ and x₂ are values in the interval [x,y] respectively
Step-by-step explanation:
Well, first to determine the average rate of change of a function, you should have the interval of the values of x for the function.
So lets assume you have a function;

And the interval as [1,3]
Then the average rate of change for the function f(x) will be;

where x₁ and x₂ are the interval coordinates x,y respectively. In this case x₁=1 and x₂=3
To find the average rate of change in this example will be;
