. That is:
If 
and 
, then 
is:
Given that presence of the expression 
, then:
and
The value of a is obtained by applying the definition of logarithms:
Finally, the value of k is found by direct comparison:
Answer:
say that you had 30 half of 30 is 15, so split it equally
Step-by-step explanation:
Cost of the compact disc player = 50 pounds
Percentage of VAT = 17 1/2%
= 35/2%
Then
Amount of VAT that needs to be given = (35/2)% * 50
= (35/200) * 50
= 1750/200
= 8.75
So the amount of VAT that has to be given is 8.75 pound
Amount that needs to be paid for the compact disc = (50 + 8.75) pound
= 58.75 pound.
So the total amount that needs to be paid for the compact
disc is 58.75 pounds
Answer: 5x + 2y = -2
Step-by-step explanation:
Change 5x+2y=12 to slope intercept: 2y = 12 - 5x, y = -5x/2 + 6
A parallel line has the same slope, so the line we try to find is y = -5x/2 + b.
Substitute (-2, 4) in and get 4=5+b, so b = -1.
Therefore the answer is y = -5x/2 - 1, or if you want it in the original form it would be 2y = -5x - 2 ---> 5x+2y = -2.
