1. x=71
This is solved by isolating the radical then raising each side of the equation to the power of its index.
2. NO SOLUTION
There are no values of x that make the equation true.
Gettysburg, i think i just learned this
Answer:second one I just did that
Step-by-step explanation:
The interval for which the average rate of change of f(x) is negative is; from x = 0 to x = 2.5.
For the average rate of change of f(x) to be negative, it means that the change in y and the change in x must have opposite signs.
For example, if the change in y is negative, them the change in x must be positive.
Similarly, if the change in y is positive, then change in x must be negative.
Now, the graph showing this quadratic function is missing and so i have attached it.
From the graph, the only interval at which the rate of change for y and x have opposite signs is from x = 0 to x = 2.5.
In this interval, we see that x is increasing from 0 to 2.5 which is positive change while y is decreasing from 1 to -3 which is negative change.
