Answer:
y = -3x + 12
Step-by-step explanation:
<u><em>Very similar to the other question i answered, by here's a step by step anyway in case you find it helpful : )</em></u>
There are lots of different methods to do these types of questions, but this is the way i like to do it.
Coordinate (x1, y1) : (1, 9) and Gradient (m): -3
Start with this generic equation:
y- y1 = m(x-x1)
Substitute in the values they have given you:
y - (9) = -3(x-1)
This becomes:
y -9 = -3x +3
Keep solving by moving the 10 over to the other side:
y = -3x + 3 +9
y = -3x + 12
An easy way to double check:
1) the coefficient of x is the slope. We got -3x, and the slope is -3, so that's correct.
2) Substitute x=1 into the equation, and we get 9, which is the exact coordinate that they gave us. This is also right.
Hope this helped : )
Hi reminder!!! just wanted to let you know that you are beautiful DONT pay attention to what other people say Ily :)
-2 + 2.5= 0.5 and -7 + (-1.5) = -8.5
so B is at (0.5, -8.5)
Answer: you would have $1772 at the end of 10 years.
Step-by-step explanation:
The formula for continuously compounded interest is
A = P x e (r x t)
Where
A represents the future value of the investment after t years.
P represents the present value or initial amount invested
r represents the interest rate
t represents the time in years for which the investment was made.
e is the mathematical constant approximated as 2.7183.
From the information given,
P = $1200
r = 3.9% = 3.9/100 = 0.039
t = 10 years
Therefore,
A = 1200 x 2.7183^(0.039 x 10)
A = 1200 x 2.7183^(0.39)
A = $1772 to the nearest dollar
