Answer:
Equation of the axis of symmetry is: x = 3
Step-by-step explanation:
The equation
is the equation of a parabola, of the form
whose vertex is located at the x-coordinate:
Then, for our case the x position of the given parabola, is:
Then the equation of the axis of symmetry, which is a vertical line that goes through the vertex, would be given by:
x = 3
Answer:
To find the value of y, you would put your expressions (12y+3, and 51 equal to each other, because they are both the same length)
12y+3=51
12y=48 (51-3=48)
y=4 (divide both sides by 12, 48/12=4)
Then to find x you want to find the missing degree of the triangle
we already know that one degree is 63 and the other is 56,
A triangle equals 180 degrees
56+63=119
Then you want to subtract 119 from 180 to find out the missing degree
180-119=61
x=61 degrees
y=4 and x=61
Hope this helps ;)
