Y = –3x2 – 12<br><br> Axis of symmetry:
kicyunya [14]
<h3>Answer:   x = 0</h3>

Work Shown:

y = -3x^2 - 12 is the same as y = -3x^2 + 0x + (-12)

Compare this to y = ax^2 + bx + c, and we'll find that

a = -3

b = 0

c = -12

Plug the 'a' and 'b' values into the formula below and simplify

h = -b/(2a)

h = -0/(2*(-3))

h = 0

The x coordinate of the vertex is x = 0, so the axis of symmetry is also x = 0.

The axis of symmetry lays perfectly on top of the y axis.

-2x+6y=6<br> -7x+8y=-5<br><br> Solve for x and y
tangare [24]
-2x+6y=6
-7x+8y=-5

2(7x+8y=-5)
-7(-2x+6y=6)
Distribute
14x+16y=-10
14x-42y=-42
eliminate
-26y=-32
divide
y=1.2

-2x+6(1.2)=6
-2x+7.4=6
subtract 7.4 on both sides
-2x=-1.4
divide
x=0.7

I believe this is right
