Answer:
$42.49
Step-by-step explanation:
s=p−(p×d)
Where:
s
is the sales price: what we are solving for in this problem
p
is the original price: $49.99 for this problem
d
is the discount percent: 15% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as
15/100. Substituting and calculating
s gives: s =$49.99-($49.99×1510)
s=$49.99−$749.8100
s=$49.99−$7.4985 s=$42.4915 s=$42.49
rounded to the nearest cent.

D is a notation for differential. There is a d2 in your formula because in the numerator there are two differentials. The formula is thus the second derivative of a function with respect to two variables.
Answer:
(14, -2)
Step-by-step explanation:
To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:
Now we know what <em>x</em> equals. Let's substitute this into the second equation:
We can then simplify:
Given equation
Combine y terms
Add 2
Divide by -11
So, we now know the value of y = -2.
To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:
Substitute for y
Distribute 8
Add 16
So, we now know the value of x = 14.
Therefore, we know a solution to the system of equations is (14, -2).
