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.
Answer:
Gabby received 9 brown marbles.
Step-by-step explanation:
.5 is the tenth so look to the right
9 is greater than or equal to 5 so round up:
65,754.6
Answer:
Distributive Property
Step-by-step explanation:
What do you mean by answer? you cannot solve for a numerical value without setting it equal to anything.
the only thing you can do is factor out a 2
2(-x +2)
