Answer:
Step-by-step explanation:
Make both equations equal to each other and solve for the variable x:
Find two numbers that when you add them you get -3 and the product of both numbers be -4. These numbers are 1 and -4. Then:
Substitute these values into one the original equations and solve for y:
Therefore, you get that:
The percentage change in house prices between 2017 and 2018 is -1.13%.
Percentage can be described as a fraction of a number expressed as a number out of hundred. The sign used to represent percentages is %.
In order to determine the percentage change in average house price, the difference between average housing pricing in 2018 and 2017 would be divided by the average house price in 2017 and the result would be multiplied by 100.
Percentage change = [(£469538 - £474902) / £474902] x 100 = -1.13%

Answer: interest at the end of 3 years is $495.72
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 3 years
P = $3,672
R = 4.5%
Therefore
I = (3672 × 4.5 × 3)/100
I = 49572/100
I = 495.72
90-x because a complementary angle is =90 degrees.
We have:
and:
so:
It is a finite sum, so it is convergent.
