Answer:

A: 114, B: 84

Step-by-step explanation:

Let A be weight of Train A, B be weight of Train B. Since A is heavier than B by 30 tons, A = B + 30. Since A + B = 198, you can substitute for A to get (B+30) + B = 198. Then simplify so 2B = 168 and B = 84.

Then plug B into A = B+30 to get A = 114.

A)<br> Identify all x-values not in the domain of<br> y=(x² – 4x²) / (3x² - 6x – 24)
True [87]

Answer:

x ≠ 4 or -2

Step-by-step explanation:

the denominator cannot be zero, so factor the bottom equation to get the zeros and those are the domain restrictions.

3x^2 - 6x - 24 ≠ 0

3(x^2 - 2x - 8) ≠ 0          (factor out a 3)

3(x - 4)(x + 2) ≠ 0            (factor equation)

x ≠ 4, x ≠ -2                     (use zero product property to find zeros)
