Question

Which statement is true? A.The equation –3|2x + 1.2| = –1 has no solution. B.The equation 3.5|6x – 2| = 3.5 has one solution. C.The equation 5|–3.1x + 6.9| = –3.5 has two solutions. D.The equation –0.3|3 + 8x| = 0.9 has no solution.

Answer 1

Answer:

none of them is true

Step-by-step explanation:

Just check each statement to see if it is true.

A. The equation -3|2x + 1.2| = –1 has no solution.

But the equation has an infinite number of solutions.

So the statement is false.

B. The equation 3.5|6x – 2| = 3.5 has one solution.

But the equation has two solutions, so the statement is false.

C. The equation 5|-3.1x + 6.9| = –3.5 has two solutions.

But the equation has zero solutions.

So the statement is false.

D. The equation -0.3|3 + 8x| = 0.9 has no solution.

The equation has one solution..

So the statement is false.
