Answer:
x = 1
Step-by-step explanation:
The line of symmetry is defined as the x value of the vertex of a parabola.
To find the vertex of a parabola, we need to convert to vertex form.
Vertex form looks like this:
, where -h is the x value of the vertex and k is the y value of the vertex.
H is also defined as 
where a is the coefficient of x squared and b is the coefficient of the x term.
The coefficient of the x squared term is 1 and the coefficient of b is -2.
Plugging in, we get 
, which is equal to 1. This can then be plugged into the equation as
, but k doesn't matter because all we need is the x-term. Now, our x-term is negative h, which is negative negative one, which is positive one. Therefore, our answer is x = 1.
Given:
A coordinate pair was dilated from (-3, 2) to (-6, 4).
To find:
The scale factor.
Solution:
We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.
The value of scale factor is:
Therefore, the scale factor is 2.
9] Rocky Falls would be 13.4°F at sunrise.
Use the equation 23.1 + (-9.7) = x, where x is the temperature at sunrise (13.4)
23.1 + (-9.7) = 23.1 - 9.7
Solve so that x = 13.4
10] Jamie originally had $263.25 in her account.
Just add how much she spent (135.75 + 32) to how much she ended up with (95.5)
135.75 + 95.5 + 32 = 263.25
If you are asking how much she has if she started out with $95.50 before going to the Mets game,
95.5 - (135.75 + 32) = -$72.25
Or 95.5 - 135.75 - 32, same result of -72.25
