Answer and Step-by-step explanation:
To solve for x, we need to first add 20 to both sides, and then add 2x to both sides.
2x > 20 + 4
Combine like terms.
2x > 24
Divide each side by 2.
x > 12
So, the answer is:
Any value of x that is greater than 12.

Answer:
Step-by-step explanation:
Given the quadratic function
we have to find the leading coefficient of given quadratic equation.
The coefficient of i.e a is known as the leading coefficient.
Comparing given equation with the standard equation, we get
a=-2
Using the formula I=Pxrxt
P is the principal amount, $9000.00.
r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
t is the time involved, 1....year(s) time periods.
So, t is 1....year time periods.
To find the simple interest, we multiply 9000 × 0.05 × 1 to get that:
The interest is: $450.00
So the balance will be $9450.00 at the end of the first year.
