Answer:
y = -2x + 1
Step-by-step explanation:
Then any equation of the form y = -2x + b, b≠1 will create a system with no solution. Hence the values of m and b are m = -2, b ≠ 1.
hope i helped
we know that
the volume of a rectangular prism is equal to
![V=L*W*H](https://tex.z-dn.net/?f=%20V%3DL%2AW%2AH%20)
where
L is the length of the box
W is the width of the box
H is is the height of the box
in this problem we have
![V=x^{3\ }+11x^2+20x-32](https://tex.z-dn.net/?f=%20V%3Dx%5E%7B3%5C%20%7D%2B11x%5E2%2B20x-32%20)
![W=x-1](https://tex.z-dn.net/?f=%20W%3Dx-1)
![H=x+8](https://tex.z-dn.net/?f=%20H%3Dx%2B8)
![L=?](https://tex.z-dn.net/?f=%20L%3D%3F)
<u>Find the length of the box</u>
Using a graph tool-------> we will determine the roots of the equation of volume
see the attached figure
the roots are
![x=-8\\x=-4\\ x=1](https://tex.z-dn.net/?f=%20x%3D-8%5C%5Cx%3D-4%5C%5C%20x%3D1)
so
![x^{3\ }+11x^2+20x-32=(x+8)*(x+4)*(x-1)](https://tex.z-dn.net/?f=%20x%5E%7B3%5C%20%7D%2B11x%5E2%2B20x-32%3D%28x%2B8%29%2A%28x%2B4%29%2A%28x-1%29%20)
therefore
<u>the answer is</u>
the length of the box is equal to ![(x+4)](https://tex.z-dn.net/?f=%20%28x%2B4%29%20)
