Answer 2

To calculate the expression $P(5 - x) - P(6 - x)$ where $P(x) = 5x - 4$, we substitute the given expression for $P(x)$ into the original expression and simplify:

$P(5 - x) - P(6 - x) = (5 \times (5 - x) - 4) - (5 \times (6 - x) - 4)$

Let's simplify step by step:

1. $P(5 - x)$ $= (5 \times (5 - x)) - 4$ $= (25 - 5x) - 4$ $= 25 - 5x - 4$ $= 21 - 5x$

2. $P(6 - x)$ $= (5 \times (6 - x)) - 4$ $= (30 - 5x) - 4$ $= 30 - 5x - 4$ $= 26 - 5x$

Now, we'll compute the difference: $P(5 - x) - P(6 - x) = (21 - 5x) - (26 - 5x)$

Distribute the negative sign: $= 21 - 5x - 26 + 5x$

The $5x$ terms cancel out: $= -5$

So, $P(5 - x) - P(6 - x) = -5$.
