-5/8(-3/8 minus one fourth)
Ne4ueva [31]

The value of  \frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )= 25/64

<h3>What is fraction?</h3>

A fraction simply tells us how many parts of a whole we have. You can recognize a fraction by the slash that is written between the two numbers.

\frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )

= -5/8 (-3/8 -2/8)

= -5/8 (-5/8)

= 25/64

Thus, \frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )= 25/64

Find the inverse of the given function
xenn [34]

For this case, we must find the inverse of the following function:

f (x) = \frac {5x + 1} {- x + 7}\\x\neq 7

To find the inverse we follow the steps below:

y = \frac {5x + 1} {- x + 7}

We rewrite the denominator:

y = \frac {5x + 1} {- (x-7)}\\y = - \frac {5x + 1} {(x-7)}

We exchange variables:

x = - \frac{5y + 1} {(y-7)}

We solve for y:

We multiply on both sides of the equation by (y-7)

x (y-7) = - 5y-1\\xy-7x = -5y-1

We subtract xy on both sides of the equation:

-7x = -5y-1-xy

We add 1 to both sides:

-7x + 1 = -5y-xy

We factor for y:

-7x + 1 = y (-5-x)

We divide both sides by (-5-x):

y = \frac {-7x + 1} {- 5-x}

So, we have:

f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}

Answer:

f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}

x\neq -5

Yvette is considering taking out a loan with a principal of $16,200 from one of two banks. Bank F charges an interest rate of 5.
umka21 [38]
Hi there
First find the monthly payment of each offer to see which monthly payment is lower
The formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value
PMT monthly payment
R interest rate
K compounded monthly 12
N time
Solve the formula for PMT
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]

Bank F
PMT=16,200÷((1−(1+0.057÷12)^(
−12×8))÷(0.057÷12))
=210.53

Bank G
PMT=16,200÷((1−(1+0.062÷12)^(
−12×7))÷(0.062÷12))
=238.21

From the above the monthly payment of bank f is lower than the bank g
And since the lifetime of bank g is lower than bank f the answer is
b. Yvette should choose Bank F’s loan if she cares more about lower monthly payments, and she should choose Bank G’s loan if she cares more about the lowest lifetime cost.

Good luck!

A number,x, decreased by the sum of 2x and 5 represent what equation
Annette [7]
We set up this expression that we have to simplify. Although, to make it an equation, we set the expression given equal to the variable y, making this a function too.
y=x-(2x+5)
distribute the negative symbol
y=x-2x-5
combine like terms
y=-x-5
and that is our final answer
