To find the vertex of a quadratic equation, determine the coefficients of the equation, then use the vertex x-coordinate formula to find the value of x at the vertex. Once the x-coordinate is found, plug it into the original equation to find the y-coordinate.

Step-by-step explanation:
Answer:
price of a computer that she could afford R 9230.769
Step-by-step explanation:
Given data
amount pay = R500 per month = 500 × 24 = R 12000 total pay
time period =24 months = 24 /12 = 2 years
rate = 15 % per annum
to find out
price of a computer that she could afford
Solution
we know formula
Amount Paid = Principal × (1+(RT/100))
put value principal pay and R and T and we get
principal = Amount / (1+(RT/100))
principal = 1200 / (1+(15 ×2 )/100))
principal = 9230.769
price of a computer that she could afford R 9230.769
The width in inches would be 12, because of the formula:
length x width = perimeter
so you would do it reverse!
perimeter/length = width
so, 144/12 = 12
