What you have to find is what numbers add to -6 and multiply to 9. these numbers would be -3 and -3 (-3+-3=-6, -3*-3=9). substitute these in for -6x as x^2-3x-3x+9=0. then factor out c and three to get x(x-3)-3(x-3)=0. x-3=0 in both cases, so x is three.

Ostrovityanka [42]

Hello from MrBillDoesMath!

Answer:

 (g o f)(0) cannot be evaluated

Discussion:

(g o f)(0) = g ( f(0))  if it exists but f(0) is not defined (as division by zero is not defined) so   (g o f)(0) cannot be evaluated

Thank you,

The equation y = 1/5x represents a proportional relationship. Explain how you can tell the relationship is proportional from the
andre [41]
If a graph is proportional then the line will go through the origin at point (0, 0). If the equation is proportional then it will be in the form of y=kx with no other operations after. The constant of proportionality is another way to say the slope and in your specific equation the slope would be 1/5.
