Answer:
f=42
fdb=104
Step-by-step explanation:
-x - y = -5
y = x + 1
-x -(x + 1) = -5
-x - x - 1 = -5
-2x = -5 + 1
-2x = -4
x = -4/-2
x = 2
y = x + 1
y = 2 + 1
y = 3
solution is : (2,3)
it's plural so axes*
and in pilar coordinates, the axes are circular so they never intersect but the centre point is still called origin.
