8 0

Answer:


Step-by-step explanation:

2x - y = 8

<u> x + y = - 2 </u>

3x       = 6

3x /3    = 6/3   Dividing bot sides by 3 to find x.

x = 2

Plug in the value of x to find y.

2 ( 2) - y = 8

4 - y = 8

-y = 8 - 4

- y = 4

y = -4

The solution: ( 2, -4)

The graph shows f(x)=(1/2)and its translation, g(x).
san4es73 [151]

The translation of four units up describes the transform function g(x) option first is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The question is:

The graph shows f(x)=(1/2)ˣ and its translation, g(x).

Which describes the translation of f(x) to g(x)?

  • Translation of four units up
  • Translation of five units up
  • Translation of four units to the right
  • Translation of five units to the right

The graph is attached please refer to the picture.

We have the equation of the function f(x):

\rm f(x) = (\dfrac{1}{2})^x

From the graph, we can see the graph of the function f(x) is shifted up 4 units because the y-intercept of the graph g(x) is (0, 5)

g(x) = f(x) + 4

\rm g(x) = (\dfrac{1}{2})^x + 4

Thus, the translation of four units up describes the transform function g(x) option first is correct.
