In November, the average temperature at the North Pole is -8.3 degrees Fahrenheit. In December, the average temperature at the North Pole is 7.7 degrees Fahrenheit colder than November's average temperature. In January, the average temperature at the North Pole is 1 1/4 times colder than December's average temperature. What is the average temperature, in degrees Fahrenheit, at the North Pole in January?

-17.25

Step-by-step explanation:

So first you add -8.3 and -7.7, from there you get -16.

-1 1/4 would be -1.25 as a decimal. So all you do is add -16 and -1.25 and you get -17.25 as your answer

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
