1. The quadratic formula is shown below:

2. Given the quadratic equation given in the problem, you have that:

3. Therefore, when you substitute the values shown above, you obtain the following result:


Answer:
5 cartons of eggs
3 packages of steaks
Total cost=$55
Step-by-step explanation:
Hi, to answer this question we have to find the least common multiple of
6 (number of eggs in a carton) and 10 (number of ham steaks in each package)
LCM = 30
6 12 18 24 30
10 20 30 40 50
Since each carton of eggs (x) has 6 eggs, that expression must be equal to 30(eggs) to find the number of cartons.
6 (x ) = 30
Solving for x
x = 30/6
x = 5 cartons
Same process for the steak, where y= number of packages .
10 y = 30
y = 30/10
y=3 packages
Since each carton costs $2 and each package of steaks cost $15:
Total Cost =x 2+y 15
Replacing with the values of x and y calculated
Total cost = (5)2 + (3)15 = 10+45 =$55
Feel free to ask for more if needed or if you did not understand something.
Step-by-step explanation:
y = x² - 16
x² = y + 16
x = sqrt(y + 16) because x is non-negative.
Hence the inverse function is f^(-1)(x) = sqrt(x + 16). (A)
