If I varies inversely with R and I = 0.25 when R = 18, which equation should be used to show this relationship?
pashok25 [27]
Inverse relationships are of the form xy=k or if you prefer  y=k/x so to find the constant we can say:

18(0.25)=k=4.5

So you could say: IR=4.5 or I=4.5/R

3y-x=3 and x is four times the value of y what is the value of x-y?
Aleonysh [2.5K]

Answer:

x - y = -9

Step-by-step explanation:

from the equation

3y - x = 3

and x is four times the value of y

i.e  x = 4y

put x  = 4y into the first equation

we have;

3y  - 4Y = 3

-Y = 3

Divide both sides by -1

we have

y = -3

so put y = -3 in the 2nd equation

i.e x = 4y

x = 4 × -3

x = -12

therefore x = -12 and y = -3

so tho find x - y

we have

-12 - (-3)

= -9

therefore x - y = -9

Preston signed up for overdraft protection at his bank. This bank charges an overdraft fee of $30 for insuffcient funds. Preston
Marianna [84]

Answer:

-$32

Step-by-step explanation:

Given that

Overdraft fee = $30

Preston Balance = $50

Total expenditure = $52

As per the given question the solution of new balance is provided below:-

To reach the new balance of Presont's first we need to find out the overdraft balance which is as follows:-

Overdraft balance = Balance - Total expenditure

= $50 - $52

= -$2

Since there is a balance of $50 but Pretson purchased for $52 value that results -$2 overdraft balance. In order to determine the new balance we simply added the overdraft fee and overdraft balance which is shown in negative sign.

Now according to the question the New balance of Presont's = Overdraft balance - overdraft fee

= -$2 - $30

= -$32
