At the start of 2014 lucys house was worth ?200 000. The value of the house increased by 5% every year. Workout the value of her

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.

A system of equations has definitely many solutions. If 2y-4x=6 is one of the equations, which could be the other equation?

NISA [10]

The given equation is ⇒⇒⇒ 2y - 4x = 6

∴ 2y = 4x + 6 ⇒ divide all the equation over 2

∴ y = 2x + 3 and it can be written as ⇒⇒⇒ y - 2x = 3

The last equation represents a straight line with a slope = 2 and y-intercept = 3

To construct a system of equations with definitely many solutions and the equation ( 2y-4x=6 ) is one of the equations, the other equation must have the same slope and the same y-intercept.

so, the general solution of the other equation is ⇒ a ( y - 2x ) = 3a

Where a is constant and belongs to R ( All real numbers )

The system of equations which has definitely many solutions is consisting of <u>Coincident lines.</u>
