Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!
You have the following equation for the cost of renting a car for x number of miles driven:
y = 0.15x + 65
If you travel 70 miles, then, x = 70 and you obtain for the cost y:
y = 0.15(70) + 65
y = 10.5 + 65
y = 75.5
Hence, the cost of renting a car to drive 70 miles is $75.5
Answer:
Step-by-step explanation:
Use the formula for the volume of a cylinder:
Volume= B times height
Being "B" the area of the cylinder's base (a circle of radius 4.5 ft.
Therefore the area of the base is:
So the volume of the cylinder is:
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.
