Use the distributive property.
1/7(105 + r) = 20
15 + (1/7)r = 20
Then subtract each side of the equation by 15.
15 + (1/7)r = 20
(1/7)r = 5
Divide both sides by 1/7.
(1/7)r = 5
r = 35
So, the answer to this question is r is equal to 35.

The required domain of the inverse function is x ≤ 0. Hence option D is correct.
f(x) = -x^2
<h3>What are functions?</h3>
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.
Inverse of function f(x) = -x^2
y = -x^2
x = √-y
Now,
Inverse function of f(x) is √-x
Its domain is define as less than or equal to zero.
Thus, the required domain of the inverse function is x ≤ 0.
