45. Real Estate Appreciation Bob Michaels purchased a

Tju [1.3M]

Answer:

Since t is between 0 and 15, and the house was purchased 8 years ago, we have two pairs of values:

t = 0, V(0) = 42000
t = 8, V(8) = 67500

<u>Find the slope, m:</u>

m = (67500 - 42000)/8 = 3187.50

The value of b is 42000, since at t = 0, V = 42000

<u>So the equation is:</u>

V = 3187.50t + 42000

The graph is attached.

When V = 72500, t = 9.6 (approximately)

When V = 74000

74000 = 3187.5t + 42000
3187.5t = 32000
t = 32000/3187.5
t ≈ 10 years (rounded down)

When V = 80250

80250 = 3187.5t + 42000
3187.5t = 80250 - 42000
3187.5t = 38250
t = 38250/3187.5
t = 12 years

What is the value of x in the equation 8x – 2y = 48, when y = 4

9966 [12]

Answer:

Seven(7)

Step-by-step explanation:

8x-2y=48

8x-2(4)=48

8x-8=48

8x=48+8

8x=56

Divide both sides by 8

8x/8=56/8

x=7
