Solve this equation for x. round your answer to the nearest 0 = ln (x+6)
MissTica

Answer: x=-5

Step-by-step explanation:

To solve this exercise you need to remember the following:

e^{lnx}=e^{lny} → x=y

Therefore, keeping the above on mind, you can solve for x as following:

e^0=e^{ln(x+6)}

e^0=x+6

Remember that, by definition: a^0=1, then you have:

1=x+6

Subtract 6 from both sides of the equation.

Then the value of x is:

1-6=x+6-6\\x=-5

What is k+3 3/4 = 5 2/3 - 1 1/3
zhenek [66]
K+3 3/4=5 2/3-1 1/3
k+3 3/4=4 1/3
lets find the lcm first then multiply both sides by it but first change it to improper fraction
LCM is  12

[k+15/4]=[13/3]12
12k+45=52
12k=7
k=7/12

Put the steps in correct order to prove that if x is irrational, then 1/x is irrational using contraposition.
SOVA2 [1]

Answer:

The correct order is:

a

c

d

b

Step-by-step explanation:

First, let's write 1/x in a convenient way for us:

a) Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.

Now we assume that 1/x is rational (we want to prove that this implies that x will be also rational and because we know that x is irrational assuming that 1/x is rational will lead to an incongruence), then:

c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.

Now we know that we can write x as a quotient of two integers, we need to imply that, then the next one is:

d) Observe that x is the quotient of two integers with the denominator nonzero.

And that is the definition of rational, then we end with:

b) Hence x is rational.

Which is what we wanted to get.
