Answer:

6 + 8y

Step-by-step explanation:

Write the given expression:  uv/4 + 8y

Multiplication and division must be done before addition or subtraction.  Therefore, if u = -12 and v = -2, uv/4 = (-12)(-2)/4 = 6

and therefore,  uv/4 + 8y  =  6 + 8y

Until you have provided a value for y, 6 + 8y cannot be evaluated; 6 + 8y is already in simplest form.

In the 1980s an average mortgage rate was around 18.5 how much less per month would a 150000 30 year mortgage by today if the cu
lianna [129]

Answer:

  $1516.69 per month less

Step-by-step explanation:

The formula for the monthly payment A on a loan of principal P, annual rate r, for t years is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 18.5% loan, the monthly payment is ...

  A = 150000(.185/12)/(1 -(1 +.185/12)^(-12·30)) ≈ 2321.92

For the 5% loan, the monthly payment is ...

  A = 150000(.05/12)/(1 -(1 +.05/12)^-360) ≈ 805.23

The mortgage at 5% would be $1516.69 less per month.

Describe fully the single transformation that maps triangle A onto triangle B
Vera_Pavlovna [14]

Answer:

Reflection over the x-axis

Step-by-step explanation:

To get from Triangle A to Triangle B, Triangle A must be reflected over the x-axis. On Triangle A, the left-most point is at (1, -2). The corresponding point on Triangle B is at (1, 2). The rule for reflecting over the x-axis is (x, y) -> (x, -y). So, (1, -2) -> (1, 2).

I hope this helps :))

I would think B. Because he is still $47 in debt and he lent 13 so he has 13 left.
