Answer:
(x1, y1) = (1, 3)
(x2, y2) = (4, 12)
Step-by-step explanation:
y= x^2 - 4
y= 5x - 8
(substitute the value for y)
x^2 - 4 = 5x - 8
(solve the equation) 
x = 1
x = 4
(substitute the values) 
y = 5 × 1 - 8 
y = 5 × 4 - 8 
(solve the equations) 
y = -3
y = 12
( the possible solutions are) 
x1, y1 = 1, -3 
x2, y2 = 4, 12 
(check the solutions)
-3 = 1^2 - 4
-3 = 5 × 1 - 8
12 = 4^2 - 4
12 = 5 × 4 - 8
(simplify) 
-3 = -3 
-3 = -3 
12 = 12 
12 = 12 
(the ordered pairs are the solutions)

Answer:
angles one and two are supplementary angles and adjacent angles
Step-by-step explanation:
Definitions:
Supplementary angles: two angles that add to 180 deg
Adjacent angles: two angles that have a common side and a common vertex (corner point)  and don't overlap
complementary angles: two angles that add up to 90 deg
vertical angles: two angles that are directly opposite from each other, formed by intersecting lines
