Answer:
The solution is (-17,80.5) and (1,8.5)
Step-by-step explanation:
Equation 1 : ![y=\frac{1}{2}x^2+4x+4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7Dx%5E2%2B4x%2B4)
Equation 2: ![y = -4x+12.5](https://tex.z-dn.net/?f=y%20%3D%20-4x%2B12.5)
Substitute the value of y from equation 2 in equation 1
Equation 1 : ![y=\frac{1}{2}x^2+4x+4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7Dx%5E2%2B4x%2B4)
After substitution :
![-4x+12.5=\frac{1}{2}x^2+4x+4\\\frac{1}{2}x^2+8x+4-12.5=0\\\frac{1}{2}x^2+8x-8.5=0\\x^2+16x+17=0\\x=-17,2](https://tex.z-dn.net/?f=-4x%2B12.5%3D%5Cfrac%7B1%7D%7B2%7Dx%5E2%2B4x%2B4%5C%5C%5Cfrac%7B1%7D%7B2%7Dx%5E2%2B8x%2B4-12.5%3D0%5C%5C%5Cfrac%7B1%7D%7B2%7Dx%5E2%2B8x-8.5%3D0%5C%5Cx%5E2%2B16x%2B17%3D0%5C%5Cx%3D-17%2C2)
Substitute the value of x = -17
y = -4x+12.5
y = -4(-17)+12.5
y=80.5
Substitute the value of x = 1
y = -4(1)+12.5
y=8.5
Hence the solution is (-17,80.5) and (1,8.5)
