The answer is C.
Explanation:
(First, make sure the to finish solving the quadratic equation)
x^2 + 2x - 16 = 12x
x^2 - 10x - 16 = 0
(a, b and c are the coefficients of x^2, x and the constant respectively)
a = 1, b = -10, c = -16
(We can substitute this into the quadratic equation. +- means + or -)
x = [- b +- sqrt(b^2 - 4ac)]/2a
= [- (-10) +- sqrt(100 + 64)]/2
= [10 +- sqrt(164)]/2
(So C is the answer)
Answer:
A
Step-by-step explanation:
it is going from low to high
Answer:
Step-by-step explanation:
We would apply the formula for determining simple interest which is expressed as
I = PRT/100
Where
I = interest at the end of t years
r represents the interest rate.
P represents the principal or initial amount deposited.
t represents the number of years of investment.
From the information given,
P = 1000
R = 2%
T = 5 years
Therefore,
I = (1000 × 2 × 5)/100
I = $100
The total amount in the account after 5 years would be
1000 + 100 = $1100
Y=4 is the answer for this
