The temperature outside dropped 13 degrees farenhiet in 7 hours. the final temperature was -2 degrees farenhiet. what was the starting temperature?

13 + (-2) = 15

Step-by-step explanation:

13 is greater because the absolute value (13) is greater than the absolute value of -2 (2)

Which is why it is a negative answer, you need to add to get to the temperature it was before it dropped. Because both numbers are negative you just need to add to solve it.

Which is 15

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
