Answer:
5.5%
Step-by-step explanation:
To find the interest rate, use the equation: I = prt
I = Interest = $6,600
p = principal = $15,000
r = rate = unknown
t = time = 8 years
Now plug the numbers into the equation.
6,600 = 15,000 * r * 8
6,600 = 120,000 * r
Now isolate the variable by dividing both sides of the equation by 120,000.
0.055 = r
Now change the rate to a percent by moving the decimal point 2 digits to the right.
5.5% = r OR r = 5.5%
Answer:
k = 2/3 x
y = 2/3.
Step-by-step explanation:
y = kx where k is a constant
y = 2 when x = 3 so:
2 =k*3
k = 2/3.
The equation is y = 2/3 x.
When x = 1
y = 2/3 * 1 = 2/3.

Answer:
the value of c is 25
Step-by-step explanation:
b/2a= 10/2(1)= 10/2= 5
(5)^2 = 25
x^2 + 10x + 25 = (x + 5)^2
