Answer:

\large\boxed{(f+g)(x)=-8x-6}

Step-by-step explanation:

(f+g)(x)=f(x)+g(x)\\\\f(x)=-5x-4,\ g(x)=-3x-2\\\\\text{Substitute:}\\\\(f+g)(x)=(-5x-4)+(-3x-2)\\\\=-5x-4-3x-2\qquad\text{combine like terms}\\\\=(-5x-3x)+(-4-2)\\\\=-8x-6

The vertex of this parabola is at 2, -1 When the y-value is 0 the x value is 5 what is the coefficient of the squared term in th
Olegator [25]

Answer:

\large \boxed{\sf \frac{1}{9}}

Step-by-step explanation:

\sf y=a(x-h)^2+k

\sf Vertex = (h,k)

y-value is 0 and the x value is 5

h = 2

k = -1

\sf 0=a(5-2)^2+-1

Solve for \sf a (the coefficient of the squared term).

\sf 0=a(3)^2+-1

\sf 0=9a-1

\sf 9a=1

\displaystyle \sf a=\frac{1}{9}

The coefficient of the squared term in the parabola equation is 1/9.
