Answer:
f(x) = 11 - x
Step-by-step explanation:
We have to find a function that has a graph as x + y = 11.
Now, the equation given is
x + y = 11
⇒ y = 11 - x
So, if we consider x as an independent variable and y as a dependent variable whose values are dependent on the values of x, then er can write y = f(x) = 11 - x
So, the function f(x) = 11 - x has the same graph as x + y = 11. (Answer)
Answer:

Step-by-step explanation:
So we have the equation:

First, let's subtract 9 from both sides:

Divide both sides by -4:

Add 1 to both sides:

Divide both sides by 2:

And we're done!
Answer:
31.25 seconds
Step-by-step explanation:
Examine division
11.6 + 24.4 = 36 m < 50m
and 36 + 37.2 - 73.2m > 50m
50 - 36 = 14m
14 * 23.25/37.2 = 8.75 seconds
7.25 + 15.25 + 8.75 = 31.25 seconds
so it would take him 31.25 seconds to swim 50 meters.
