Answer:
(0,-10)
Step-by-step explanation:
Using the equation y = mx = b where b is the y-intercept,
we can find that the "b" in y=|3x-10|+1 is -10
So the y-intercept is -10 or at the coordinates (0,-10)
Answer:
The correct answer is option
![d.\ x=-i, i, 3 \sqrt{5}\ or\ -3 \sqrt{5}](https://tex.z-dn.net/?f=d.%5C%20x%3D-i%2C%20i%2C%203%20%5Csqrt%7B5%7D%5C%20or%5C%20-3%20%5Csqrt%7B5%7D)
Step-by-step explanation:
The given equation has a degree 4 (Highest power of
):
is the given equation which can be written as:
![(x^2)^2-44x^2-45=0 ...... (1)](https://tex.z-dn.net/?f=%28x%5E2%29%5E2-44x%5E2-45%3D0%20......%20%281%29)
Let
and putting it in equation (1):
![t^2-44t-45=0 \\](https://tex.z-dn.net/?f=t%5E2-44t-45%3D0%20%5C%5C)
Solving the above quadratic equation in variable
:
![\Rightarrow t^2-45t+t-45=0 \\\Rightarrow t(t-45)+1(t-45)=0\\\Rightarrow (t+1)(t-45)=0\\\Rightarrow t =-1\ or\ 45](https://tex.z-dn.net/?f=%5CRightarrow%20t%5E2-45t%2Bt-45%3D0%20%5C%5C%5CRightarrow%20t%28t-45%29%2B1%28t-45%29%3D0%5C%5C%5CRightarrow%20%28t%2B1%29%28t-45%29%3D0%5C%5C%5CRightarrow%20t%20%3D-1%5C%20or%5C%2045)
We know that
So, ![x^{2} =-1\ or\ x^{2}= 45](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%3D-1%5C%20or%5C%20x%5E%7B2%7D%3D%2045)
1. Solving ![x^{2} =-1](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D-1)
![\Rightarrow x = +\sqrt{-1}\ or\ -\sqrt{-1}\\\Rightarrow x = i\ or\ -i](https://tex.z-dn.net/?f=%5CRightarrow%20x%20%3D%20%2B%5Csqrt%7B-1%7D%5C%20or%5C%20%20-%5Csqrt%7B-1%7D%5C%5C%5CRightarrow%20x%20%3D%20i%5C%20or%5C%20%20-i)
2. Solving ![x^{2} =45](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D45)
![\Rightarrow x = +\sqrt{45}\ or\ -\sqrt{45}\\\Rightarrow x = 3\sqrt{5}\ or\ -3\sqrt{5}](https://tex.z-dn.net/?f=%5CRightarrow%20x%20%3D%20%2B%5Csqrt%7B45%7D%5C%20or%5C%20%20-%5Csqrt%7B45%7D%5C%5C%5CRightarrow%20x%20%3D%203%5Csqrt%7B5%7D%5C%20or%5C%20%20-3%5Csqrt%7B5%7D)
Hence, correct answer is:
![x=-i, i, 3 \sqrt{5}\ or\ -3 \sqrt{5}](https://tex.z-dn.net/?f=x%3D-i%2C%20i%2C%203%20%5Csqrt%7B5%7D%5C%20or%5C%20-3%20%5Csqrt%7B5%7D)
