Answer:

  (x, y) = (1, ±2)

Step-by-step explanation:

To solve this pair of equations, one can add the second equation to twice the first:

  2(2x +y^2) +(3x -2y^2) = 2(6) +(-5)

  4x +3x = 12 -5 . . . . simplify a bit

  7x = 7 . . . . . . . . . . . collect terms

  x = 1  . . . . . . . . . . . . divide by 7

Then y can be found from the first equation:

  y^2 = 6 -2x = 6 -2(1) = 4

  y = ±√4 = ±2

The solutions are ...

  (x, y) = (1, -2)   or   (1, 2)

What describes the transformation of g(x)=3(2)-x from the parent function f(x)=2x
Mama L [17]

Answer:

Reflect across the y-axis, stretch the graph vertically by a factor of 3

Step-by-step explanation:

The question has certain errors, in fact the functions are the following:

g (x) = 3 * (2) ^ - x

f (x) = 2 ^ x

The transformation that we can do to obtain the translated graph, Are given in 2 steps, which are the following:

1. When x is replaced by -x, then it reflects the graph on the y axis.

2. 3 multiplies with the function, it means that it stretches the main function vertically in 3 units.

So to summarize it would be: Reflect across the y-axis, stretch the graph vertically by a factor of 3
