Answer:

x = 8, y = 4

Step-by-step explanation:

  • x + 4 = 3y

x = 3y-4

  • 3 + 2x - 2y = 11

2x - 8 = 2y

x - 4 = y

x = y + 4

substitute top equation to this equation

3y-4 = y+4

2y = 8

y = 4

now substitute this into second equation

x = y + 4

x = 8

check answer with first equation

x = 3y-4

8 = 3(4) - 4

8 = 8; correct

Please help me thank you :)

The function on the table is decreasing on the interval [-2, 0).

<h3>Over what interval is the function shown in the table decreasing?</h3>

A function is decreasing if, as x increases, f(x) decreases.

We can see that at x = -2, f(-2) = 12.

Then at x = 0, f(0) = 0.

And for the value after that:

x = 1, f(1) = 3

So now the function increases. Then we conclude that the function is decreasing on the interval [-2, 0), and after that the function increases.
