2nd Option
Step-by-step explanation:
Standard Form: ax² + bx + c
This can be modified to fit any degree polynomial, as long as the highest degree is first, and then decreasing. So our answer is B.
The sweater prices have reduced by 80% due to the special.
Step-by-step explanation:
Step 1; Cost before reduction was $30. The cost after reduction was 6$. Cost reduced= cost before reduction - cost after reduction
Cost reduced= $30 - $6 = $24
Step 2; We must find how much of the cost was reduced from the initial cost i.e. how much $6 is to $30. To do this we must convert it into a percentage. We divide the $6 with the $30 to get a value. This value must be multiplied with a 100 to be converted into a percentage.
Cost by which sweater was reduced= 24/30 * 100 = 0.8 * 100 = 80%.
So the price of the sweater was reduced from $30 to $6 which means there was a reduction of 80%.
It is either a or d maybe if wrong sorry
Answer:
k = 3
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 18 when x = 6 , then
18 = 6k ( divide both sides by 6 )
3 = k
