Answer:
The required equation is c = 1.59 - s
Step-by-step explanation:
Here, s represents the sales price per pack and c represents the cost saving,
Also, the regular price per pack = $ 1.59,
Since,
Cost saving = Regular price - sales price
⇒ c = 1.59 - s
Which is the required equation that is used to determine how much money is saved if the pack is bought today.
Answer:
f(x) = (x -(-3))(x -(-4))
Step-by-step explanation:
The function can be written as the product of binomial terms whose values are zero at the given zeros.
(x -(-3)) is one such term
(x -(-4)) is another such term
The product of these is the desired quadratic function. In the form easiest to write, it is ...
f(x) = (x -(-3))(x -(-4))
This can be "simplified" to ...
f(x) = (x +3)(x +4) . . . . simplifying the signs
f(x) = x^2 +7x +12 . . . . multiplying it out

Answer:
3
Step-by-step explanation:
You want a number that if it is multiplied by 3 1/3 the result will be 10. Let the number be x
3 1/3 * x = 10 Change to a mixed number
10/3 * x = 10 Multiply by 3/10
(10/3)*x * 3/10 = 10 * 3/10 Combine
x = 10*3 / 10 Simplify
x = 30/10 = 3
Answer:
B
Step-by-step explanation:
tan(30)=n/(5*sqrt(3))
=> n=5
