Answer:
There are no solutions
Step-by-step explanation:
6x-3-9x-2
6x-9x = -3x
-3-2 = -5
the the equation is: -3x-5
This is child's play.
So, basically:
Y=Length of foot
X= Length of your forearm.
This is simple. Your equation is Y=0.860x + 3.302
So, if you have a forearm (x) that is 17 inches long, then plug in x as 17. This leaves you to evaluate for Y.
New equation: Y=0.860(17) +3.302
Work it out, you get: Y=14.62 + 3.302
Work that out, you get: Y= 17.922 inches long.
And of course, Y is the foot.
So, your answer: If the forearm is 17 inches long, then the foot is 17.922 inches long. Simple.
So, part 2:
Rate of change. Well, you need slope then, because that's the same thing.
Y=mx+b, Where m=slope
Your answer turns to be 0.860 inches per length of arm, for rate of change.
Skipping the data, as that's only something you'd know.
Yes, it is indeed a function. There can't be any exponents greater than 1 on the placeholder, and it's obviously not a straight line if you plug it in.
So yeah, it's a function.

The value of the output r(-3) in the given function is 2.
<h3>How to Interpret Graphs?</h3>
When we talk about graphs like this, it is pertinent to note that the x-values are the input values which would give us corresponding y-values which are the output values.
Now, we want to find r(-3) from the graph. This means we want to find the value on the y-axis when x = -3.
From the given graph, we see that when x = - 3, it is traced that the value of the output is y = 2.
Thus, the value of the output r(-3) in the given function is 2.
