You don't say what the tax rate is. Supposing it were 5%, then your bill would be 1.05($29.99) = $32.49.
Step-by-step explanation:
y = mx + b, where m is the line's slope and b is the y-intercept.
We have m = -1. When x = -1, y = 2/3.
=> (2/3) = (-1)(-1) + b, b = 2/3 - 1 = -1/3.
Hence the value of b is -1/3.

Rate if Change is zero because the velocity still remains the same
Rewrite it in the form a^2 - b^2, where a = 2x and b = 5
(2x)^2 - 5^2
Use the Difference o Squares: a^2 - b^2 = (a + b)(a - b)
<u>(2x + 5)(2x - 5) </u>
