Rewrite the equation below in standard form.
-3x+6y=12
C. -x+2y=4
if you take each term and divide them by 3 you will get the c
Answer:
The amusement park needs to pay at least $98.40 to 225 employees. So the minimum price they need to charge to pay all the employees is 98.40 x 225
Step-by-step explanation:
Profit minimum= employee pay x employee amount
98.40 x 225
After multiplication, profit minimum needs to be= $22140
Divide profit minimum by guests to get price per ticket
22140/1000 guests
$22.14= price of ticket for minimum profit

Answer:
The curve is a circle of radius 9 centered at the point (0,9) and the equation is
Step-by-step explanation:
Proceed as follows:
Take . Then
Multiply both side by . Then
Use the following substitution . Then
By cancelling out x on both sides we get the following equation
or
Recall that given a expression of the form we can complete the square by adding an substracting the amount . So, we get . In our case, we will complete the square for y, then
. Then
or
.
Recall that the equation of a circle is given by where (h,k) is the center of the circle and r is the radius. In our case we have h=0, k = 9 and r = 9. So it is a circle of radius 9 centered at the point (0,9)
