6 0

Answer:To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

X = – 2y – 1 x = – 5y + 5

motikmotik

Answer:

x = -5

y = 2

Step-by-step explanation:

x = – 2y – 1

= -x - 2y - 1

-x - 2y = 1

x = – 5y + 5

= -x - 5y + 5

-x - 5y = -5

-x - 2y = 1

-x - 5y = -5

___________--

3y = 6

y = 6/3

y = 2

-x - 2y = 1

-x - 2(2) = 1

-x - 4 = 1

-x = 1 + 4

-x = 5

x = -5

Answer:

$x = -4$

Step-by-step explanation:

Take out 3x from both sides:

5x - 3x = 3x - 3x

2x = 0

2x + 9 = 1

Take out 9 from both sides:

9 - 9 = 1 - 9

0 = -8

Divide 2 from both sides:

$\frac{2x}{2} = \frac{-8}{2}$

$x = -4$
