What is the solution to 2x+3y=9 over X-2y=1

1 answer:

6 0

Assuming this is what you mean:
2x + 3y = 9
x - 2y = 1

-2(x - 2y = 1)
-2x + 4y = -2
2x + 3y = 9
7y = 7
y = 1

2x + 3(1) = 9
2x + 3 = 9
2x = 6
x = 3

Solution (3, 1)

Which statement best describes the effect on the graph of y = (x – 9)2 if the equation is changed to y = (x + 9)2? The graph mov

Answer:

Third option: The graph moves left 18 units.

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

If $f(x)+k$ , the function is shifted up "k" units.

If $f(x)-k$ , the function is shifted down "k" units.

If $f(x+k)$ , the function is shifted left "k" units.

If $f(x-k)$ , the function is shifted right "k" units.

In this case, we can observe that graph of $y = (x - 9)^2$ is changed to $y = (x + 9)^2$

Since:

$-9+18=9$

We can conclude that the function $y = (x - 9)^2$ is shifted left 18 units to get the function $y = (x + 9)^2$ .

Answer:

Step-by-step explanation:

The function is y = 17x. Then if x = 1, y = 17; if x = 2, y = 34, and so on, which agree with the table. The other questions are difficult or impossible to read. Please try to obtain and share better quality images.
