Answer:
the first option - 48s + 4.75
Step-by-step explanation:
- x + y = 7
y = x + 7
slope = 1
perpendicular slope = -1
at point (-1, -1),
y = mx + c
-1 = -1 (-1) + c
-1 = 1 + c
c = -1 -1
c = - 2
equation:
y = -x -2
y + x = -2 or - x - y = 2
Answer:
X is an algebraic variable that has no defined value.
