So you know the new equation must have the same slope as the old equation since they're parallel to one another. Next just simply take the slope and the point given and plug them into the point-slope formula and you have your new equation:
y-y1=m(x-x1) --- Point-Slope Formula
y+5=2(x-4)
y+5=2x-8
y=2x-13 --- Answer
Answer is the last one

Mid ocean ridges are formed when two tectonic plates are drifting away from each other. This is known as a divergent or constructive plate boundary. Mid ocean ridges are formed as two oceanic plates move away from each other. The plates move as a result of convection cells in the mantle that generate convection currents. An example of a midocean ridge is the Mid Atlantic ridge where African plate drifts away from the north and south American plates.
Answer:
a) see below
b) 40x20 meters
Step-by-step explanation:
Write down what you know:
- The area of the enclosure is length*width, so
- The length of the fencing is 80 meters, so
Now we have to combine these two equations above, and get rid of y in the process.
First rewrite the second as:
Then substitute for y in the first:
b) To maximize A, find the zero of the first derivative:
So y = (80-40)/2 = 20 meters.
With this you need to find the unit rate so divide 48 by 4 to get 12, so the scuba diver descended 12 ft. per min.
