The rate of change is -0.9.
Since the function f defined by f(x) = -0.9x + 665 is in slope-intercept form
f(x) = mx + b, we identify the coefficient on x to be the slope. And the slope is the rate of change.
For every one unit increase in x, y decreases by 0.9 units.

Answer:
17
Step-by-step explanation:
In this problem, you can use the Pythagorean Theorem to find the hypotenuse, which is x. The formula for the Pythagorean Theorem is: , where <em>a </em>and <em>b </em>are the two lengths of the triangle, and <em>c</em> is the hypotenuse (which is x).
<u>Steps:</u>
-We know the two sides already, which are 15 and 8, so we can substitute <em>a </em>and <em>b </em>into the equation: (the <em>c</em> is the same as x, just letting you know)
-Then, simplify the equation to get: (I replaced <em>c</em> with x just so you can understand better that we are trying to find x, the hypotenuse)
-Add the 225 and 64 to get:
-Find the square root of both sides to get x by itself:
-Evaluate the equation to get: which simplifies to
