Jessica purchased a DVD that was on sale for 12% off. The sales tax in her county is 3%. Let y represent the original price of the DVD. Write an expression that can be used to determine the final cost of the DVD.
Answer:
is it y=12x+3
Step-by-step explanation:
x=DVD. DVD =12
The expression that represents the final price of the DVD is 0.9064y
How to determine the final cost?The given parameters are:
Discount = 12%Sales tax = 3%Original price = yThe final cost is calculated using:
Final = Original price * (1 - discount) * (1 + sales tax)
So, we have:
Final = y * (1 - 12%) * (1 + 3%)
Evaluate the expression
Final = 0.9064y
Hence, the expression that represents the final price of the DVD is 0.9064y

y=x+5, (8, 1)
Answer:
y = x - 7
Step-by-step explanation:
Parallel lines have the same gradient in this case 1 is the gradient.
Using the point (8,1) we can form our own equation.
1 will be y, 1 will be m, 8 will be x
All we have to do is find C in order to form the equation y=mx+c
1 = 1(8) + c
1 = 8 + c
C = - 7
Therefore;
y = x - 7

what is a number with exactly 10 factors? smallest number you know please!
Answer:
Step-by-step explanation:
You have to learn to state the problem exactly the way you want the answer to be.
For example, do you want all 10 factors to be the same? In which case the answer is 2^10 which means there are 10 twos multiplied together. The answer is 1024 and I think that is the smallest number with 10 factors.
Must the factors be different as in 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 11 = 39916800
Must all the factors be prime (so that they are all different)
2 * 3 * 5 * 7 * 11 * 13 * 17 * 19 * 23 * 29.
I'll bet that can't be done on an ordinary calculator without going into scientific notation.

Hey guys. I just need someone's help to clarify things with me.
As I was doing the equations, I got to:
x^-1
-----
x^13
I moved the x^-1 down to x^13 so they'd subtract. But when I did, x^-1 became positive.
So it became x^13 times x^1
Radical Rule: a^n x a^m is pretty much a^n+m
So my answer was 14.
How did x^-1 become positive in this case?
Step-by-step explanation:
Given [tex]\frac{x*x^{-2} }{x^{13}}[/tex]
= [tex]\frac{x*x^{-2} }{x^{13}} = \frac{x^{-1} }{x^{13}}[/tex]
According to the Negative Exponent Rule, [tex]a^{-n} = \frac{1}{a^{n}}[/tex]
Therefore, [tex]\frac{x^{-1} }{x^{13}} = \frac{1}{x^{1}*x^{13}} = \frac{1}{x^{13+1}}= \frac{1}{x^{14}}[/tex]
In other words, [tex]x^{-1}[/tex] became positive because of the Negative Exponent Rule. Once you bring [tex]x^{-1}[/tex] down towards the denominator, you're essentially removing its negativity and turning its exponent into a positive value. Once that takes place, then you could apply the Product Rule of Exponents onto the exponents in the denominator, where it states, [tex]a^{m}a^{n} = a^{m+n}[/tex].

The length of the field is 3 yards less than triple the width. What are the dimensions of the playing field
Answer:
45=w answer
Step-by-step explanation:
Here's what we know:
P = 2L + 2w
L = 3w + 3 (length is 3 yards more than 3 times the length)
P = 366
We have a value for length and perimeter, so plug them in:
366 = 2(3w + 3) + 2w
366 = 6w + 6 + 2w
366 = 8w + 6
360 = 8w
45 = w
