F(X) means plug in te number within the parenthesis for the given function. It's simply an equation expressed through different notation. In this case it asks you to plug in two, so you do:
-3(2)+4 = f(2)
That means that f(2)=-2.
we know that
In the right triangle RSQ
------> equation
In the right triangle RST
------> equation
equate equation and equation
therefore
the answer is

Answer:
Given the equation: 4(2x-1)+5 = 3+2(x+1) .....[1]
Distributive property states that when a number is multiplied by the sum of two numbers, then the first number can be distributed to both of those numbers and multiplied by each of them separately.
i.e,
Applying distributive property, in [1]we get;
Simplify:
.....[2]
Like terms are those terms that have the same variables and powers
Combine like terms on each side in equation [2];
8x +(-4+5) = (3+2) +2x
Simplify:
8x + 1 =5 + 2x
The terms which Carey combine are; -4 +5 and 3 + 2
Answer:
25%
6.5%
35%
Step-by-step explanation:
Given the invoice :
Bill for a pair of Jean
Jeans ______39.99
Discount ___ - 10.00
Subtotal ____ 29.99
Sales tax ____ 1.95
Total _______ 31.94
A) % of discount to the nearest %
Discount amount = % discount * price
10 = x% * 39.99
10/39.99 = x%
0.2500625 = x%
x = 0.2500625 * 100%
% discount = 25%
% of sales tax:
Sales tax amount = % tax * Subtotal
1.95 = x% * 29.99
1.95/29.99 = x%
0.06502 = x%
x = 0.06502 * 100%
x = 6.5%
Markup before discount = 60%
Markup after discount = (60 - 25)% = 35%
