Your answer would be A:x=3
Answer:
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Step-by-step explanation:
The Pythagorean Theorem is used to find a missing side length in a right triangle, and the formula
is used to find the missing side, assuming a and b are legs, while c is the hypotenuse.
Answer:

Answer:
![x=5+\sqrt{12}](https://tex.z-dn.net/?f=x%3D5%2B%5Csqrt%7B12%7D)
or
![x=5-\sqrt{12}](https://tex.z-dn.net/?f=x%3D5-%5Csqrt%7B12%7D)
Step-by-step explanation:
![x^2-10x+13=0](https://tex.z-dn.net/?f=x%5E2-10x%2B13%3D0)
![x^2-10x=-13](https://tex.z-dn.net/?f=x%5E2-10x%3D-13)
![x^2-10x+(\frac{10}{2})^2 =-13+(\frac{10}{2})^2](https://tex.z-dn.net/?f=x%5E2-10x%2B%28%5Cfrac%7B10%7D%7B2%7D%29%5E2%20%3D-13%2B%28%5Cfrac%7B10%7D%7B2%7D%29%5E2)
![x^2-10x+(5)^2=-13+(5)^2](https://tex.z-dn.net/?f=x%5E2-10x%2B%285%29%5E2%3D-13%2B%285%29%5E2)
![x^2-10x+25=-13+25\\x^2-10x+25=12](https://tex.z-dn.net/?f=x%5E2-10x%2B25%3D-13%2B25%5C%5Cx%5E2-10x%2B25%3D12)
Factor.
![(x-5)^2=12](https://tex.z-dn.net/?f=%28x-5%29%5E2%3D12)
Extract the square root.
![x-5=\frac{+}{} \sqrt{12}](https://tex.z-dn.net/?f=x-5%3D%5Cfrac%7B%2B%7D%7B%7D%20%5Csqrt%7B12%7D)
Add 5
![x=5+\sqrt{12}](https://tex.z-dn.net/?f=x%3D5%2B%5Csqrt%7B12%7D)
or
![x=5-\sqrt{12}](https://tex.z-dn.net/?f=x%3D5-%5Csqrt%7B12%7D)
Step-by-step explanation:
We find the equation of the solid blue line:
The line decreases by 1 unit for every 3 units across.
=> Slope of line = -1/3.
Also the y-intercept is 1.
=> Line equation: y = -1/3 x + 1.
We see that the graph below this line is shaded.
Therefore all y-values below or on the line are represented by the graph.
=> y <= -1/3 x + 1.
The answer is y <= -1/3 x + 1.
