Answer:

<h2>The right answer is the second graph.</h2>

Step-by-step explanation:

All choices are attached.

Each graph is representing a system of equations which is not linear, because a parabola is not a linear relation.

According to the problem, we have to choose the system which solution is (-1,1). To do so, we just have to observe which graph has an interception point at (-1,1).

You can observe that the second graph has the interception point at (-1,1), that is, both functions has that point in common, because they intercept there.

Therefore, the right answer is the second graph.

What is... X/2 - 13 = 1
kow [346]
X ÷ 2 - 13 = 1
Write the division as a fraction
\frac{1}{2}x - 13 = 1
Multiple both sides of the equation by 2
2 \times  \frac{1}{2}x  \times  - 2 \times 13 = 12
Reduce the number with greatest common divisor 2
x - 2 \times 3 = 2
Multiply the numbers
- 2 \times 13
Then u will have
x - 26 = 2
Move constant to the right by adding its opposite sides
x - 26 + 26 = 2 + 26
Eliminate the opposites
- 26 + 26
Then you have
x = 2 + 26
Add the numbers
x = 28
