<h3>Answers:</h3>

The first ordered pair is   ( -4 , -3 )

The second ordered pair is   ( 8, 3 )

=================================================

Explanation:

The first point is (x,-3) where x is unknown. It pairs up with y = -3 so we can use algebra to find x

x-2y = 2

x-2(-3) = 2 ... replace every y with -3; isolate x

x+6 = 2

x = 2-6

x = -4

The first point is (-4, -3)

---------------------------

We'll do something similar for the other point. This time we know x but don't know y. Plug x = 8 into the equation and solve for y

x-2y = 2

8-2y = 2

-2y = 2-8

-2y = -6

y = -6/(-2)

y = 3

The second point is (8, 3)

Answer:

  1. c = -4.5
  2. z = 20
  3. x = -12
  4. a = -4/7

Step-by-step explanation:

A way to do this that will always work is ...

  • eliminate parenthses and collect terms
  • subtract any constants from the left side
  • subtract any variable terms from the right side
  • divide by the coefficient of the variable

1.

  • 8c -11 -6c = -2
  • 2c -11 = -2
  • 2c = 9
  • c = 4.5

2.

  • 3z +4 -2z -9 = 15
  • z -5 = 15
  • z = 20

3.

  • 12 -4x +18 = 36 +4x +18 -6x
  • 30 -4x = 54 -2x
  • -4x = 24 -2x
  • -2x = 24
  • x = -12

4.

  • 36a -9a -5 = 6a -17
  • 27a -5 = 6a -17
  • 27a = 6a -12
  • 21a = -12
  • a = -12/21 = -4/7

Madeleine owes $36,000 to a private lender. The debt grows with 12% annual interest that compounds every week. How much will Mad
viva [34]

Answer:

A= $40584.28      

Step-by-step explanation:

P = 36000

r = 12% = 0.12

n = 52 weeks

t = 1

A = P(1 + \frac{r}{n})^{nt}\\

   =36000(1 + \frac{0.12}{52})^{52 \times 1}\\\\=36000 (1.002307)^{52}\\\\=36000 \times 1.12734\\\\=40584.28

1.A house worth $250,000 has an coinsurance clause of 90 percent. The owners insure the property for $191,250. They then have a
Arisa [49]

1. Multiply the value of the house by the percent:

250,000 x 0.9 = 225,000

Divide the amount the owner insured by the clause amount:

191,250/225,000 = 0.85

Multiply that by the amount of damage:

0.85 x 80,000 = 68,000

They will receive $68,000

2. Follow the same steps as above:

180,000 x 0.75 = 135,000

101,250 / 135,000 = 0.75

0.75 x 50,000 = 37,500

They will receive $37,500
