Answer:

Yes

Step-by-step explanation:

To determine if (- 2, - 5) is a solution to the equation.

Substitute x = - 2 into the right side of the equation and if the value obtained is equal to the y- coordinate of the point then it is a solution.

y = - 2 - 3 = - 5 ← hence (- 2, - 5) is a solution to the equation

No because (-2, -5) is negative and the y coordinate needs to be positive.

Write the inverse of the rational function f(x)=15x +50 over x+5

Whitepunk [10]

F(x) = 15x + 50/x + 5
y = 15x + 50/x + 5
x = 15y + 50/y + 5
x(y + 5) = 15y + 50
xy + 5x = 15y + 50
5x - 50 = 15y - xy
5x - 50 = y(15 - x)
y = 5x - 50/15 - x

SO

The inverse of f(x) = 5x - 50 over 15 - x
