The value of the function f(x) = x² + 6x - 9 when x = -5 is -14.
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Given that:
f(x) = x² + 6x - 9
When x = -5:
f(-5) = (-5)² + 6(-5) - 9 = -14

Answer:
#1 is 3/6 or 1/2
#3 is 1/6
#5 is 4/6 or 2/3
Step-by-step explanation:
Since we know that the two lines are parallel because of alternate interior angles (5x-20)=3x
then solve for x
5x-20=3x
-20=-2x
x=10°
Answer: -1
