The answer is approximately 11.18.
Answer: even
Step-by-step explanation:
A function is even if f(x)=f(-x), and odd if f(x)=-f(-x). If a function satisfies neither of these, it is neither even nor odd.
![f(x)_=-6x^{2}-5x^{2}-2=-11x^{2}-2\\\\f(-x)=-11(-x)^{2}-2=-11x^{2}-2\\\\\therefore f(x)=f(-x)](https://tex.z-dn.net/?f=f%28x%29_%3D-6x%5E%7B2%7D-5x%5E%7B2%7D-2%3D-11x%5E%7B2%7D-2%5C%5C%5C%5Cf%28-x%29%3D-11%28-x%29%5E%7B2%7D-2%3D-11x%5E%7B2%7D-2%5C%5C%5C%5C%5Ctherefore%20f%28x%29%3Df%28-x%29)
Therefore, the function is <u>even</u>.
Answer:
y = (-3/2)x + 5
Step-by-step explanation:
Collect like terms
2y = -3x +10
Divide both sides by 2
2y/2 = -3x/2 + 10/2
y = (-3/2)x + 5
The quadratic formula is the result of completing the square for ax^2+bx+c=0 when a,b, and c are unknown values. This result is:
x=(-b±√(b^2-4ac))/(2a), we have x^2-x-2=0 so
x=(1±√(1+8))/2
x=(1±√9)/2
x=(1±3)/2
x=-1 and 2
