What is the solution to the system of equations?
elixir [45]

Answer:

No solution

Step-by-step explanation:

-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9\\\\

Lets consider the equation 2.

Here we multiply the LHS and RHS with (-1).

-3x-4y-3z=-7\\-(2x-6y+2z)=-3\\5x-2y+5z=9\\\\

Hence,

-3x-4y-3z=-7\\-2x+6y-2z=-3\\5x-2y+5z=9\\\\

When we add the equations we get,

0x+0y+0z=-10+9\\Hence,\\0=-1

As 0 doesn't equal to -1, answer is d) No solution

In the equation y=ab^(x-h) +k how does the value of k affect the graph
Ainat [17]

Answer:

  • if k > 0 then the graph of the given equation will get shifted upward by k units.
  • if k< 0 then the graph of the given equation will get shifted downward by k units.

Step-by-step explanation:

We have been given the equation  y=ab^(x-h) +k and we have to state that how the value of k affect the graph.

We know that if we add/subtract some constant in the function value then the translation of the parent graph occurs in the vertical direction.

In other words, the parent graph either get shifted upward or downward depends on the value of the constant.

Therefore, we have

  • if k > 0 then the graph of the given equation will get shifted upward by k units.
  • if k< 0 then the graph of the given equation will get shifted downward by k units.
