Answer:
(since there is no percentage given i will provide two alternate answers one including percentage and one exclusive of percentage)
cost of TV inclusive of tax = $500
we first multiply the tax with total amount
$500 * 5.5
= $500 * 55/10
=$500 * 11/2
= $250 * 11
=$2750
original price of TV = $2750
alternate answer assuming there is a percentage sign with 5.5
the amount of tax on TV is 5.5%
we first multiply the percentage of tax with total amount
$500 * 5.5/100
=$27.5
original price of TV = $500 - $27.5
= $472.5
Step-by-step explanation:
A function assigns the values. The value of f(-3) and f(3) + f(-3) is 8 and -8, respectively.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given the function f(x)=-x²-4x+5, therefore, the value of f(x) when the value of x is -3 is,
f(-3) = -(-3)² - 4(-3) + 5
f(-3) = -9 + 12 + 5
f(-3) = 8
Now, the value of f(x) when the value of x is 3 is,
f(3) = -(3)²-4(3)+5
f(3) = - 9 - 12 + 5
f(3) = -16
further, the value of f(3) + f(-3) is,
f(3) + f(-3) = -16 + 8
f(3) + f(-3) = -8
Hence, the value of f(-3) and f(3) + f(-3) is 8 and -8, respectively.

Answer:
Step-by-step explanation:
Find dy/dx of the ellipse 
at (2,3)
Using Implicit Differentiation
Differentiate both sides of the equation with respect to x
isolate the term dy/dx
Evaluate at point (2,3)
For x=2, y=3
First of all, standard form means it should be this form ax+by=c
The equation for the line is
y= 1/4x-1========>Multiply each term by 4
y (4) = 1/4(4)x-1(4)
4y = 4/4x-4
4y=x-4=========>Subtract x from both sides
4y-x=x-x-4
4y-x=-4 OR X-4Y=4
Your answer is A.
