Sea level is 0
robert dives 40 ft.....-40
he then rises 23 ft.....-40 + 23 = -17
he then dives 19 ft to meet Sam....-17 - 19 = -36
together they rise 31 ft...-36 + 31 = - 5
they are 5 ft below sea level <==
Answer A is the only one that seems to make sense to me id choose A
Distribute
y+10+c=z
minus y from both sides
10+c=z-y
minus 10 both sides
c=z-y-10
The value of Ry= -x (P) is P' = (4, 6)
<h3>How to determine the transformation?</h3>
The point is given as:
P = (-6, 4)
The transformation Ry= -x (P) means tha:
(x, y) = (y, -x)
So, we have:
P' = (4, 6)
Hence, the value of Ry= -x (P) is P' = (4, 6)
