Question

|-4|+|-3x| при x=2,4

Answer 1

|-4| + |-3x| = |-4| + |-3×2,4| = 4 + |-7,2| = 4 + 7,2 = 11,2.

Answer 2

To evaluate the expression |-4| + |-3x| at x = 2 and x = 4, you simply substitute the values of x into the expression and perform the calculations:

For x = 2: |-4| + |-3x| = | -4 | + |-3 * 2| = 4 + | -6 | = 4 + 6 = 10

For x = 4: |-4| + |-3x| = | -4 | + |-3 * 4| = 4 + | -12 | = 4 + 12 = 16

So, the values of the expression at x = 2 and x = 4 are 10 and 16, respectively.
