Answer:
c
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
on edge
The equation 3.4|0.5x – 42.1| = –20.6 will have one solution.
The equation = 0 will have no solutions.
The equation |2x – 10| = –20 will have two solutions.
The equation |0.5x – 0.75| + 4.6 = 0.25 will have no solutions.
The equation = 5 will have infinitely many solutions.
Using a graph tool
Let's proceed to analyze each case
case a) The equation will have two solutions
Is true
The solutions are
see the attached figure N
case b) The equation will have one solution
Is False
The equation has no solution
The term
always will be positive
case c) Is not a equation
case d) The equation will have two solutions.
Is False
The equation has no solution
The term
always will be positive
case e) The equation |0.5x – 0.75| + 4.6 = 0.25 will have no solutions.
Is True
The left side of the equation always will be greater than or equal to
case f) The equation = 5 will have infinitely many solutions.
Is not a equation
therefore
the answer is
case a) and case e) are true
