We have a number line as indicated in the figure above. From this figure we know that the x-values increase from left to right. So we need to write the solution that matches the previous graph. Taking a look on the graph we see that $x$ begins in -3 and closes in 8, that is, $x$ takes values from -3 to 8. In a mathematical language this is given by the following statement:

 $x \in [-3,8]$

Which shows the first step in the solution to the equation log₂x + log₂(x - 6) = 4?

iren [92.7K]

log was used calculate big numbers before calculators

log is a re-arranged way to show a number with an exponent

example

log₂ 16 = 4 means 2^4 = 16

logx(Z) = y means x^y=Z

log(x-6)/log(2) + log(x)/log(2) = 4

(log(x-6)+ log(x))/log(2) = 4

(log(x-6)+ log(x)) = 4log(2)

(log(x-6)x) = log(16)

x=8

Joe has to take two quizzes tomorrow. He has only enough time to study for one of them. The science quiz has 6 true or false que

Answer:

C) English

Step-by-step explanation:

I don't really know how to explain it, so I'll show you instead.

For science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

So,

0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 = 0.016

For English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

So,

0.25 x 0.25 x 0.25 x 0.25 = 0.004

They will have to study English (0.004) because it is lower than science (0.016).

Graph this inequality on the number line. x ≤ 2.6

pantera1 [17]

x ≤ 2.6 would look like this on the number line, the 2.6 part would be shaded in as well and not left open since x is less than OR EQUAL to 2.6
