Galina-37 [17]

Answer:

The value of Lucys house  at the start of 2017 is 231525.

Step-by-step explanation:

It is given that the initial value of Lucys house is 200,000. The  at the start of 2017.

The exponential function is defined as

P=P_0(1+r)^t

Where, P₀ is initial value, r is growth rate, t is time in years.

The value of house is defined by the function

P=200000(1+0.05)^t

Where, t is number of years after 2014.

P=200000(1.05)^t

The difference between 2017 and 2014 is 3 years.

P=200000(1.05)^3=231525

Therefore the value of Lucys house  at the start of 2017 is 231525.

Ne4ueva [31]

Answer:

X=25

Step-by-step explanation:

Remove parentheses

7x - 5x - 40= 10

Merge the similar terms

2x - 40= 10

Constantly move to the right side and change characters

2x = 10 + 40

Addition

2x = 50

Divide both sides of the equation by 2

x = 25
