Answer:
OPTION A: 3x - 1 = ± 5
Step-by-step explanation:
We have (3x - 1)² = 25
In OPTION A, Square root is taken on both sides.
This gives us: 3x - 1 = ± 5. And this is the logical follow - up of the previous step.
IN OPTION B: (a - b)² is wrongly expanded. So, this can not be the next step.
In OPTION C: The square root is taken only on the LHS but not on the RHS. So, it is eliminated.
In OPTION D: The square is expanded on LHS whereas on the RHS square root is taken. So, it is not correct and is eliminated.
Therefore, the correct option is A.
<span>A) y=-2x+19
B) y=x+7
Multiplying B) by -1
B) -y = -x -7 then adding it to A)
A) y = -2x + 19
3x = 12
x = 4
y = 11
