Malloy solved the equation −5x − 16 = 8; his work is shown below. Identify the error and where it was made. −5x − 16 = 8 Step 1:

−5x − 16 + 16 = 8 + 16 Step 2: −5x = 24 Step 3: -5x/5=24/5 Step 4: x =24/5 Select one: a. Step 1: He should have subtracted 16 from each side. b. Step 1: He should have divided both sides by −5. c. Step 3: He should have multiplied both sides by −5. d. Step 3: He should have divided both sides by −5.

<span>−5x − 16 = 8                   Proof=Given
</span><span>−5x − 16 + 16 = 8 + 16   Proof=Addition Property of Equality
</span>−5x = 24                         Proof=Addition Property of Equality
<span>-5x/5=24/5                      This is where we find his fault. You have to divide by whatever the number that alters the variable is. In this case, that's -5. The answer is therefore D. Step 3: He should have divided both sides by 5.

Let f be a continuous function defined on the interval [0,1] such that f(0) = f(1). Show that there exists a number 0 &lt;= a &l
Leni [432]

Explanation:

In order to prove that affirmation, we define the function g over the interval [0, 1/2] with the formula g(x) = f(x+1/2)-f(x) .

If we evaluate g at the  endpoints we have

g(0) = f(1/2)-f(0) = f(1/2) - f(1) (because f(0) = f(1))  

g(1/2) = f(1) - f(1/2) = -g(0)

Since g(1/2) = -g(0), we have one chance out of three

  • g(0) > 0 and g(1/2) < 0
  • g(0) < 0 and g(1/2) > 0
  • g(0) = g(1/2) = 0

We will prove that g has a zero on [0,1/2]. If g(0) = 0, then it is trivial. If g(0) ≠ 0, then we are in one of the first two cases, and therefore g(0) * g(1/2) < 0. Since f is continuous, so is g. Bolzano's Theorem assures that there exists c in (0,1/2) such that g(c) = 0.  This proves that g has at least one zero on [0,1/2].

Let c be a 0 of g, then we have

0 = g(c) = f(c+1/2)-f(c)

Hence, f(c+1/2) = f(c) as we wanted.
