They payed $1,785 dollars in the second installment.
Answer:
-40
Step-by-step explanation:
Since x is 10 you need to multiply 10*-4 which equals -40.
Use the formula I = Prt. Plug $2300 into P.
Plug 7.5% (decimal form is 0.075) into r.
Plug 10 into t.
Your simple interest after 10 years is $1725
I think you mean y=ab^x.
First, plug in the values of x=2 and y=24 for the first equation, and x=3 and y=48 for the second one:
24 = ab^2
48 = ab^3
divide equation 2 by equation 1:
2 = b^1
or, more simply:
2 = b
now plug b into one of the equations to get "a":
24 = a*2^2
24 = a*4
6 = a
So, the answer is y = 6(2)^x
(I think you need to specify the power of x in your answers)
