Answer:

y = -2x + 4

Step-by-step explanation:

Equation in point slope form:

y - 2 = -2(x - 1)

y - 2 = -2x + 2

y = -2x + 4  ..............<------------------------------- slope intercept form

If AZ is a midsegment of WXY, find XZ<br> A.7<br> B.9<br> C.12<br> D.14
Deffense [45]
Since it's mid segment, WZ and ZX are equal

2x + 10 = 5x + 4

Solve for x

6 = 3x

2 = x

Plug that in for 5x + 4

5(2) + 4

10 + 4

Y=4x-18<br><br> Find ordered pairs of intercepts of each line
Masja [62]

The ordered pairs for the intercepts are as follows:

x intercept = 9/2

y intercept = -18

In order to find either of these you must put 0's in for the other variable. So, to find the x intercept, we start by putting 0 in for y.

y = 4x - 18

0 = 4x - 18

-4x = -18

x = 9/2

To find the y intercept, we put a 0 in for x.

y = 4x - 18

y = 4(0) - 18

y = 0 - 18

y = -18

A certain family can afford a monthly mortgage payment of $1,340.00. With an APR of 5.25% per annum, what is the maximum mortgag
irina [24]

Answer:

  $198,859.03

Step-by-step explanation:

The amortization formula is good for this. Fill in the given numbers and solve for the unknown.

 A = P(r/n)/(1 -(1 +r/n)^(-nt))

where A is the monthly payment, P is the principal amount of the loan, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.

  1340.00 = P(0.0525/12)/(1 -(1 +0.0525/12)^(-12·20)) ≈ 0.00673844·P

  P ≈ 1340/0.00673844 ≈ $198,859.03

The family can afford a loan for $198,859.
