Determine the axis of symmetry for the function f(x)=3(x+4)^2 -6

x = -4

Step-by-step explanation:

To determine the axis of symmetry, we need to find the vertex point.

Since the equation is already in vertex form, we can easily tell that the vertext point is (-4,-6)

We know the axis of symmetry is going to be vertical, and vertical lines are in the form of "x = ...".  

Since we know x value of the vertex is -4, we know the line of symmetry will be x = -4

For question one its 8

Step-by-step explanation: Let A be the variable for Amanda! The amount of money she has for x amount of time. We know that lisa has $13 and she is spending .50 every game. The equation for this would be L=13-0.5x. SO to solve this problem of when they both will have the same amount of money use the equation. 15- 0.75x=13 - 0.5x then you will switch the equation around. So the next step would look like 15-13= -0.5x + 0.75x! Then you'll get 2=0.25x change that to a fraction and you'll get 1/4 and 8=x!

Im so sorry if this is confusing!
