PLEASE HELP! is slope = undefined the same as y = 0?

An undefined slope is NOT the same as y= 0, since it is a vertical line. The x-coordinate never changes even if the y-coordinate is different. There is no run.

£54 in a ratio 4:5 can someone help

ludmilkaskok [199]

So when you have something like 'split up £54 in ratio 4:5', it really just means split £54 into 4 parts and 5 parts. But we can't do that without working out 1 part.

So the way to find 1 part is to add up all the parts (4 + 5) and divide 54 by that number.

So 4 + 5 is 9, and 54 divided by 9 is 6.

So if 1 part is 6, that means 4 parts is 4 times 6, which is 24.

Equally, if 1 part is 6, 5 parts is 5 times 6, which is 30.

Therefore, £54 split up in a ratio of 4:5 is 24:30.

Step by step for 7,9, 11. EVEN IF U CANT DO ALL, u can help with 1 or 2. Ill mark brainly.

KATRIN_1 [288]

Answer:

7) $4 \ log_3(x) - 4 \ log_3(y)$

9) $5log_4(7) - 5log_4(12)$

11) $5log_5 \ (x) - log_5 \ (y)$

Step-by-step explanation:

$log_3 (\frac{x}{y})^{4}$

----------------------------------------------------------------------------------------------------

Use Logarithm of a Quotient which states

$log_b \frac{M}{N} = log_b M-log_bN$

And also use Logarithm of a Power which states

$log_b\ M^{n} = n\log_bM$

----------------------------------------------------------------------------------------------------

So using these two properties,

7. $4 \ log_3(x) - 4 \ log_3(y)$

----------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------

For #9, use the same logarithm propertied

$log_4(\frac{7}{12})^5 = 5log_4(7) - 5log_4(12)$

----------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------

#11 is also the same concept

$log_5\ \frac{x^5}{y} = 5log_5 \ (x) - log_5 \ (y)$

It is not - 5 log5(y) since only x is to the power of 5 not y

----------------------------------------------------------------------------------------------------

Hope this is what you were looking for and helps you! Have a nice day/night :)

If a=bc-d, find d given that a=-16, b=3, c=5

Andrews [41]

Answer:

<h2>d = 31</h2>

Step-by-step explanation:

a = bc - d

Substitute a = -16, b = 3 and c = 5:

-16 = (3)(5) - d

-16 = 15 - d <em>subtract 15 from both sides</em>

-16 - 15 = 15 - 15 - d

-31 = -d <em>change the signs</em>

31 = d
