The temperature dropped 18°f in 3 hours. the final temperature is -7°f. what was the
starting temperature? explain how you found your answer.

11 °F

Step-by-step explanation:

The problem explains the last temperature is -7 °F and in the process the temperature dropped 18 °F, we can then make a simple equation for the starting temperature

ST-18°F=FT

ST: starting temperature

FT: final temperature

ST-18=-7

ST=-7+18=11 °F

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

c. side angle side. u shares the same sides
