Zeroes are when f(x)=0
0=x^2+9x+20
factor
0=(x+4)(x+5)
set each to zero
x+4=0
x=-4
x+5=0
x=-5
zeroes are f(-5) and f(-4)
The range would consist of all real numbers EXCEPT for zero
Answer:
10 Cups of Milk
Step-by-step explanation:
2/3 cup of milk --->10 cookies
x cup of milk --->150 cookies
x=((2/3)*150)/10=(2/3)*15=10 cups of milk
3x + 50 = 6x -10
add 10 to each side
3x +60 = 6x
subtract 3x from each side
60 = 3x
x = 60/3 = 20
x = 20
