<h3>Final value : x² -9x - 11</h3>════════════════════
<h3>Step by step </h3>2x + 1 = ⅕ × (x² + x - 6)
2x + 1 = ⅕x² + ⅕x - 6/5
1/5x² +1/5x - 2x - 6/5 - 1 = 0
1/5x² -9/5x - 11/5 = 0
x² - 9x - 11 = 0. #times by 5

Answer:
Average rate of change=-3
Step-by-step explanation:
The average rate of change is given by the relation between the values of f(x) and x, in two different points as follows:
In this case,
Therefore,
Answer:
Step-by-step explanation:
1. Given the integral function , using trigonometric substitution, the substitution that will be most helpful in this case is substituting x as
i.e
.
All integrals in the form are always evaluated using the substitute given where 'a' is any constant.
From the given integral, where a = 7 in this case.
The substitute will therefore be
2.) Given
cross multiplying
3.) Rewriting the given integral using the substiution will result into;
