<span>For this case we have the following functions:</span>
<span> f (x) = x + 8</span>
<span> g (x) = -4x - 3
</span>
<span> Subtracting the functions we have:</span>
<span> (f - g) (x) = f (x) - g (x)</span>
<span> (f - g) (x) = (x + 8) - (-4x - 3)</span>
<span> Rewriting:</span>
<span> (f - g) (x) = x + 8 + 4x + 3</span>
<span> (f - g) (x) = 5x + 11</span>
<span> Answer:</span>
<span> <span>D. (f - g) (x) = 5x + 11</span></span>

Answer:
11/18
Step-by-step explanation:
The desired probability is the sum of ...
... (probability of choosing a coin) × (p(heads) on that coin)
Since the coins are chosen at random, we assume the probability of choosing a given coin is 1/3. Then ...
... p(heads) = (1/3)·(1/2) + (1/3)·1 + (1/3)·(1/3) = 1/6 + 1/3 + 1/9 = (3 +6 + 2)/18
... p(heads) = 11/18
Answer:
15.92 rotations
Step-by-step explanation:
We need to find the circumference, then divide the distance of the driveway by the circumference.
C = (pi)(d)
C = (3.14)(16)
C = 50.24
400/50.24 = 7.971783 one way to the mailbox. Since it asks for the "journey to the mailbox", let's double it, giving us 15.9235669
