Answer:
-23
Explanation:
To find the value of the expression when x = -3, we simply put in -3 wherever we find x - doing this gives
which is our answer!
$394.51 is future value of money after 2 years.
What future value means?
- A current asset's future value (FV), which is based on an estimated rate of growth, is its value at a later time.
- Investors and financial planners use the future value to project how much an investment made now will be worth in the future.
The method that results in more money after 2 years is Peggy's investment.
Which method results in more money in 2 years?
The formula for calculating the future value of an investment:
FV = P (1 + r)^nm
FV = Future value
P = Present value
R = interest rate
m = number of compounding
N = number of years
Future value of Larry's investment: $350 x [1 + (0.04/4)]^(4 x 2) = $379
Future value of Peggy's investment: $350 x [1 + (0.06/12)]^(12 x 2) = $394.51

Answer:
The final price is $66.
Step-by-step explanation:
This question can be solved by a rule of three.
The initial price was of $120.
Initially, there was a discount of 15%. Then, there is another discount on the initial price. So the total discount is of 15+30 = 45%.
So the final price will be 100-45 = 55% = 0.55 of the initial price.
So
$120 - 1
x - 0.55
The final price is $66.
Answer:
Range is {y | y ≥ –11}
Step-by-step explanation:
This is quadratic equation.
<em>A quadratic equation's range can be found if we find the vertex.</em>
For quadratic equations that have a positive number in front of 
, it is upward opening and thus <u>all the numbers greater than or equal to the minimum value of vertex is the range.</u>
The formula for vertex of a parabola is:
Vertex = 
Where,
is the coefficient of 
is the coefficient of 
From our equation given, 
and 
Now, coordinate of vertex is 
coordinate of the vertex IS THE MINIMUM VALUE that we want. We get this by plugging in the value [ 
] into the equation. So we have:
Hence, the range would be all numbers greater than or equal to 
Third answer choice is the right one.
