Answer:
Here, x represents the weekly sale
As per the statement:
A salesperson earns $320 per week plus 8% of her weekly sales.
"8% of her weekly sales" means 
then;
the expression which represents her earning = 
"At least" means 
then;
the sales necessary for the salesperson to earn at least $1000 in the one week
⇒
Subtract 320 from both sides we have;

Divide both sides by 0.08 we get:

Therefore, the sales necessary for the salesperson to earn at least $1000 in the one week is: greater than or equal to $8500 i.e 
X = 3,6 : 6 = 0,6
x : 2x : 3x
0,6 : 1,2 : 1,8
Answer:
Your answer is A.
Step-by-step explanation:
Looking at the graphing two-equation: y = x^3 -3 and y = x^2+6 are up there, it can help us determine the limit of domain.
The dot is the x<=2 for equation y=x^3-3.
The circle is x>2 for equation y=x^2+6
Answer:
y=10
Step-by-step explanation:
Substitute -4 in place of x
y = -4*-4-6
y=10
