Answer:
(x-4)(x+5) or x^2+x-20
Step-by-step explanation:
If a root of the function is 4, (meaning that when y=0, x=4) it can be rewritten as x-4.
The same goes for if a root is -5. it will simplify to x+5.
These are called factors of a quadratic equation.
Put together, they look like (x-4)(x+5). Using the FOIL method, that can be simplified to x^2+x-20
Answer: The annual interest rate r= 8%

Answer:
B. x-intercept: -6, y-intercept: -4
Step-by-step explanation:
2x + 3y = -12
x-intercept when y = 0
2x = - 12
x = -6
y-intercept when x = 0
3y = -12
y = -4
