What is the equation of the axis of symmetry for the parabola y=-1/2(x+3)^2-5

Now remember that the vertex's x-coordinate is the same as the axis of symmetry. In this case, looking at the vertex form equation, the vertex's x-coordinate is -3, therefore the equation for the axis of symmetry is x = -3.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
