Answer:

D. X=7

Step-by-step explanation:

Use the order of operations to solve this problem.

First, combine like terms.

7x-5x=2x

Our equation is now 2x-3=x+4

Now, add 3 to both sides.

Our equation is now 2x=x+7

Subtract x from both sides.

x=7

The answer is D. X=7

Feel free to ask any questions.

Hope this helps!

What is the average rate of change for this exponential function for the interval from x=2 to x=4?
mario62 [17]

The equation to calculate the average rate of change is: y/x

y = f(x2) - f(x1)x = x2 - x1

x1: 1 (The smaller x value. It can be any number)x2: 2 (The larger x value. It also can be any number)f(x1): The value when you plug x1 into the function.f(x2): The value when you plug x2 into the function.

If we know this, the variables for this problem are assuming the function is 10(5.5)^x:

x2: 2x1: 1f(x2): 10(5.5)^(2) = 302.5f(x1): 10(5.5)^(1)= 55

This means:y = 302.5  - 55 = 247.5x = 2 - 1 = 1

Remember: the equation for avg rate of change is y/x

So, our average rate of change for the function on the interval [1,2] is 247.5 (y/x = 247.5/1)
