The temperature in frostville was at 50*F at midnight,and it dropped at a constant rate for the next 10 hours.

bazaltina [42]

After 10 hours the temperature is shown on the graph as 30 degrees.

50 degrees - 30 degrees = 20 degrees.

The temperature dropped 20 degrees in 10 hours.

Divide the change by the time:

20 degrees / 10 hours = 2 degrees per hour.

Because the temperature dropped, the change would be negative.

The answer is D. -2 degrees per hour.

What's the answer ?????

kow [346]

Okay, so all this question wants you to do is plug in 2 for x and solve for your output, aka y.

y = -4x² - 8

when x = 2....
y = -4(2)² - 8

y = -16 - 8
y = -24

so, when your input is 2, your output is -24.
