x.......y...1

-10..-3..1

12x -10y -15 + 120 -5y + 3x = 0
12x + 3x - 10y - 5y - 15 + 120 = 0
15x - 15y + 105 = 0 :(5)
3x - 5y + 21 = 0
m = -a/b
m = -3/-5
m(5) = 3/5

y-yo = m(x-xo)
y-14 = 3/5*(x-7)
y-14 = 3x/5 - 7/5
3x/5 - y + 14 - 7/5 = 0
3x/5 - 5y/5 + 70/5 - 7/5 = 0
3x - 5y + 70 - 7 =0
3x - 5y + 63 = 0
m(s) = -3/-5 = 3/5

lbvjy [14]

1) Split the second term in 3x^{2} -11x-20 into two terms.

3x^{2} +4x-15x-20

2) Factor out common terms in the first two terms, then in the last two terms.

x(3x+4)-5(3x+4)

3) Factor out the common term 3x+4.

(3x+4)(x-5)

yarga [219]

Answer:

$1169.45

Step-by-step explanation:

Using the formula:

P = L \Big( \dfrac{c(1+c)^n}{(1+c^n) -1} \Big)

where;

Loan amount L = 160000

number of months (n) = 20 × 12 = 240

Lets assume that the interest rate per month c = 6.25% since it is not given.

i.e. (6.25/( 100*12) ) = 5.208 × 10⁻³

∴

P = 160000 * \dfrac{5.208 *10^{-3} (1+5.208 *10^{-3})^{240}}{(1+5.208 *10^{-3})^{240}-1}

P = $1169.45
