Answer:
B)
.
Step-by-step explanation:
The vertex form of the equation is given by
.
We plug in the vertex to obtain:
.
Since the graph passes through (5,5) and (9,5), they must satisfy its equation.
.
.

Divide both sides by 4.

Therefore the equation is:
.
Answer:
Exact form: x = 3, -3/4 or Decimal form: x = .75, -3
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Exact form:
x = 3/4, -3
Decimal form:
x = .75, -3

Answer: the original amount of the loan is $52000
Step-by-step explanation:
Let P represent the original amount of the loan. We would apply the formula for determining simple interest. It is expressed as
I = PRT/100
Where
P represents the principal or the original amount of the loan.
R represents interest rate.
T represents the duration for which the loan was given in years
I represents the interest.
From the information given,
R = 5.75%
T = 4 year
After four years, the loan has increased $11960 in interest. This means that
I = 11960
Therefore,
11960 = (P × 5.75 × 4)/100
11960 = 23P/100 = 0.23P
P = 11960/0.23
P = 52000
