How do you expand In3x? Thanks!

Mathematics
1 answer:
Korvikt [17]3 years ago
5 0

Expanding ln(3x) is simple using the rules for logarithms. Because you can seperate ln(3x) as ln(3*x), that means that you can further expand it to ln(3)+ln(x). Review these logarithm rules to help you expand more logarithms!

Boxes of cereal normally cost £2.89 each, but a supermarket has a special offer: Boxes of Cereal 3 for the price of 2
Agata [3.3K]

Answer:

9 boxes

Step-by-step explanation:

Boxes of Cereal 3 for the price of 2, the the price of the 3 boxes of cereals must be : 2 × £2.89 = £5.78

Boxes Megan can buy for the offer = £20 ÷ £5.78  = 3.46 (to 3 s.f.)≈ 3

3 × 3 =9 packs

But they actually only cost : 3 × £5.78  = £17.34

Therefore after buying the offer Megan has £20 - £17.34 = £ 2.66 left, which is not enough to buy a single pack, so the answer is 9.

Which number line best shows how to solve −2 − (−10)? A number line from negative 10 to 10 is shown with numbers labeled at inte
Viktor [21]

Answer:

Ur answer is #1 = A number line from negative 10 to 10 is shown with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 2. Another arrow points from negative 2 to 8.

Step-by-step explanation:

The arrow from 0 to -2 represents the initial "-2" of the problem. <em>Adding </em>-10 would put an arrow of length 10 from that point to the left to -12. However, you are <em>subtracting </em>-10, so that arrow is reversed and goes from -2 to +8.

At what point does the line given by the following equation cross the y-axis? y = (6/9)X + 9
Elodia [21]

Answer:

D

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = \frac{6}{9} x + 9 ← is in slope- intercept form

with y- intercept c = 9

then the line crosses the y- axis at (0, 9 )
