4x + 1 = x^2 + 3x - 1
4x = x^2 + 3x - 2
0 = x^2 -x - 2
0 = x^2 -x + 1 - 3
0 = (x - 1)^2 - 3
3 = (x - 1)^2
sqrt 3=(x-1) and (-(x-1))
x = 1+sqrt 3 and 1-sqrt 3
sqrt means square root
<u>Importance of origin:</u>
The point at which the two axes intersect is called the origin. The intersecting x- and y-axes divide the coordinate plane into four sections.
The origin is at 0 on the x-axis and 0 on the y-axis. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).
The origin is used to determine the coordinates for every other point on the graph. It is generally the starting point on a grid.
In general, origin is the place where something comes from or the place where something originates.
I believe it would be 8 sense the other half is 4
Answer:
x = 77, y = 63
Step-by-step explanation:
x - 5 = 72 ( corresponding angles )
x = 77
The 3 angles on the straight line sum to 180°, that is
x - 5 + 51 + y - 6 = 180, that is
72 + 51 + y - 6 = 180
117 + y = 180 ( subtract 117 from both sides )
y = 63
