Answer:
x = 4.56
Step-by-step explanation:
57 + x + 25x + x = 180
27x + 57 = 180
27x = 123
x = 4.56
A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)
B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)
C. y = (3/2)x - 4
How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.
A, B, and F because corresponding angles are angles that are in the same position on both parallel lines.

ANSWER
EXPLANATION
The given point has coordinates A(-2,-3).
The rule for the reflection across the y-axis is
We apply this rule to obtain the coordinates of B.
Simplify the coordinates of B to get:
The rule for reflection across the x-axis is
When the point A(-2,-3) is reflected across the x-axis to obtain C, then the coordinates of C are:
