Answer 2

It seems like you've provided an expression and some values for variables x and y. The expression is a combination of absolute values and arithmetic operations. Let's break down the expression and substitute the given values:

Expression: 7|-x| - 4|3y - 3| + 4

Given values: x = -2, y = 0.8

Now let's substitute these values into the expression:

1. Substitute x = -2: 7|-(-2)| - 4|3y - 3| + 4 = 7 * 2 - 4|3y - 3| + 4 = 14 - 4|3y - 3| + 4

2. Substitute y = 0.8: 14 - 4|3(0.8) - 3| + 4 = 14 - 4|2.4 - 3| + 4 = 14 - 4|0.4| + 4

The absolute value of 0.4 is 0.4, so: 14 - 4 * 0.4 + 4 = 14 - 1.6 + 4 = 12.4 + 4 = 16.4

Therefore, when x = -2 and y = 0.8, the value of the expression 7|-x| - 4|3y - 3| + 4 is approximately 16.4.
