<em>Answer:</em>
The answer is what you have selected: (1, -5)
<em>Step-by-step explanation:</em>
To solve a system of equations by graphing, all you have to do is graph the equations and see where they intersect. It's pretty simple, especially if you use a website like Desmos. Here's a photo of my graph with the solution. (the point of intersection).
I hope this helps! Feel free to give me Brainliest if you feel like this helped. Best of luck with your assignment. :)

Answer:
1) x ≤ 2 or x ≥ 5
2) -6 < x < 2
Step-by-step explanation:
1) We have x^2 - 7x + 10, so let's factor this as if this were a regular equation:
x^2 - 7x + 10 = (x - 2)(x - 5)
So, we now have (x - 2)(x - 5) ≥ 0
Let's imagine this as a graph (see attachment). Notice that the only place that is above the number line is considered greater than 0, and that's when x ≤ 2 or x ≥ 5 (the shaded region).
2) Again, we have x^2 + 4x - 12, so factor this as if this were a regular equation:
x^2 + 4x - 12 = (x + 6)(x - 2)
So now we have (x + 6)(x - 2) < 0
Now imagine this as a graph again (see second attachment). Notice that the only place that is below 0 (< 0) is when -6 < x < 2 (the shaded region).
Hope this helps!
