The solutions to the system of equation f(x) and g(x) are and
Quadratic equations are equations that has a leading degree of 2. Given the following functions:
f(x)=2x^(2)-3x-10
g(x)=-3x^(2)+20
To solve, we will use the quadratic formula as shown below;
For the quadratic equation f(x)=2x^(2)-3x-10
a = 2
b = -3
c = -10
Substitute
For the quadratic equation -3x² + 20
a =-3
b = 0
c = 20

Answer:
The interest rate of the account is
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above and solve for r

Median is the middle value in a list of values arranged in increasing order.
The values given are :2,8,7,8,6,15,6,8,3
Arrange values in ascending order as: 2,3,6,6,7,8,8,8,15
The middle value is: <u>2,3,6,6</u>,7,<u>8,8,8,15</u>
<u>Median is 7</u>
<em>17 mm</em>
P = 50 mm
2x + 1 + x = 25
x = 8
2(8) + 1 = 17 mm
The length of the longest side is <em>17 mm</em>
