Effectus [21]

Answer:

y = 89 x = 123

Step-by-step explanation:

since they're both in standard form, its easier to do the process of elimination

x - y = 34

-x -y -212

------------------

-2y = -178

y = 89

now plug in y to any one of those two equations

x - y = 34

x - 89 = 34

x = 123

<em>to check:</em>

<em>x</em><em> </em><em>+</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>2</em><em>1</em><em>2</em>

<em>1</em><em>2</em><em>3</em><em> </em><em>+</em><em> </em><em>8</em><em>9</em><em> </em><em>=</em><em> </em><em>2</em><em>1</em><em>2</em>

<em>2</em><em>1</em><em>2</em><em> </em><em>=</em><em> </em><em>2</em><em>1</em><em>2</em>

What is the equation of the axis of symmetry of the graph of y+3x-6=-3(x-2)2+4
eimsori [14]
A graph shows the vertex to be at (1.5, 4.75).

The equation of the axis of symmetry is x=1.5.


_____
If you want to find it analytically, you can put the equation in standard form.
  y = -3(x -2)² +4 -(3x -6)
  y = -3x^2 +9x -2
This is of the form y = ax² +bx +c with a=-3 and b=9. The axis of symmetry is given by ...
  x = -b/(2a) = -9/(2×(-3)) = 3/2 . . . . . same as above
