Answer a) $73,525.00 b) $865.00 c) $2,941.00 d) $735.25 8)

Explanation / Answer

1)

y - 4 = (10-4)/(3-1) (x - 1)

or

y - 4 = 3x - 3

or

y = 3x + 1

option a) y = 3x + 1

2)

eq. is c) x = 0

3)

x + y > 4 and x > 0

i.e y>4, x>0

so, option d) (1, 6)

4)

2 [1 2 -3 0] + 3 [ 2 -3 4 2]

= [2 4 -6 0] + [6 -9 12 6]

= [8 -5 6 6]

d) [ 8 -5 6 6]

5)

y + 1 = - (x + 1)

or

y = -x - 2

a) y = - x - 2

6)

2 (x - 7) = - 30

or

2x - 14 = -30

or

2x = -16

or

x = -8

c) x = - 8

7)

$8,650 at 8 1/2% f

I = 8650 * 8.5 * 4 /100 = 2941

c) $2,941.00
