One cold night the temperature was 0 degrees at 8 p. m. the temperature dropped at a constant rate from 8 p. m. to midnight. at midnight the temperature was −16.8 degrees.

what was the temperature at 9 p. m.?

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
