You have the correct axis of symmetry value. Nice work.
Plug that x value into the equation to get...
y = -2x^2 - 12x - 10
y = -2*(-3)^2 - 12*(-3) - 10 <<-- replace every x with -3; then use PEMDAS
y = -2*(9) - 12*(-3) - 10
y = -18 + 36 - 10
y = 18 - 10
y = 8
The vertex is the ordered pair (-3, 8)
Note: the axis of symmetry is the vertical line through the vertex
Millie will have to pay the $20 back, and as she already has no money, she's now $20 in debt
B. 6/9 because 6/9 equal to 2/3 so it’s basically the same ratio
The answer is (B) 2<em>k</em><em> </em>= 18
A b c d... and x are all representing 1 unknown #. The particular letter
is not revelent unless its like f (x) =.... which just means y but g(x) sometimes means graph.
otherwise it doesn't matter at all
