Answer:
1/4 or 0.25
Explanation: Convert the mixed numbers to improper fractions, then find the LCD and combine.
2.5 pints. Look it up. That's what I would do
They're both functions because each input has exactly one output
We have three functions:
FIRST.

The slope of f(x) is 2
SECOND.
g(x) graph going through (0, -5) and (4, 3), so:
We can find the slope of g(x) as follows:

The slope of g(x) is 2
THIRD.
h(x) passes through (-1, 3), (1, 7) and (3, 11)
We can find the slope of h(x) as follows:

The slope of h(x) is 2
So, it is obvious that the three functions have the same slope 2.
The circumference of a circle is pi times D. So, 94.2/pi = 29.98 or about 30 in
