Which of the following is true regarding the solution to the logarithmic equation below?

lidiya [134]

Answer:

Option C.

Step-by-step explanation:

Note: It is given question and option "=" sing is missing. On some places it should be "=" instead of "=".

Consider the given equation is

$\log_2(x+11)=4$

Using properties of \logarithm we get

$(x+11)=2^4$ $[\because \log_ax=b\Leftightarrow x=a^b]$

$x+11=16$

$x=16-11$

$x=5$

The solution is x=5.

To check the solution, substitute x=5 in the given equation.

$\log_2(5+11)=4$

$\log_2(16)=4$

$\log_22^4=4$

$4=4$

$LHS=RHS$

Therefore, x-5 is a true solution because $\log_2(16)=4$ .

What is unit rates and how do you solve them

ratelena [41]

Answer:

Unit rates are ratios that are used to compare different quantities

Step-by-step explanation:

It really depends on what kind of unit rate you're answering. So let's say that you go to the grocery store, and potatoes are $5.50 for 5. You would divide 5.50 by 5 to get the answer $1.10. Hope this helps!

Solve the inequality and give the interval notation

laila [671]

|7 - x| >= 1

When solving for x inside an absolute value, you can set up two equations. One for the positive and one for the negative(since we’re dealing with absolutes.

We end up with:
7 - x >= 1
7 - x <= -1 (inequalities’ signs flip when multiplying or dividing by a negative.)

7 - x >= 1
7 - 1 >= x
X <= 6

7 - x <= -1
7 + 1 <= x
X>= 8

X: (-infinity, 6]U[8, infinity)
