The justification used is multiplicative property of equality because both sides are multiplied by the same value
<h3>Solving linear equations</h3>
Given the expression below
-1/3(4x^2 - 3) - 3 = 5x^2 - 2
We are to determine the justification by Anne to get the step 2 as shown
(4x^2 - 3) - 3 = -3(5x^2 - 2)
Expand
(4x^2 - 3) - 3 = -15x^2 + 6
Hence the justification used is multiplicative property of equality because both sides are multiplied by the same value

Answer:
37 million and 37037
Step-by-step explanation:
<h3>Given</h3>
- Current year online retail site visitors = 50 million
- Previous year online retail site visitors = x
- The difference = 35% increase from previous year
<h3>Solution</h3>
- x + 35% = 50 million
- x*1.35 = 50 million
- x = 50 million /1.35
- x = 37 million and 37037
<u>37 million and 37037 Americans visited online retail sites on Black Friday last year</u>
Answer:
A reflection over the y axis .
Step-by-step explanation:
Given : Transforms (a,b) to (-a,b).
To find : What type of transformation.
Solution : We have given
Parent function : (a,b) .
Transformed : (-a ,b).
Transformation rule of reflection over y axis : ( x, y) →→ ( -x ,y).
Then we can say in transformation (a,b) →→→→ (-a,b).
Therefore, A reflection over the y axis

The slopes of 2 perpendicular lines with be reciprocals with the opposite sign.
For example if you have the equation y=-5x+2, your slope is -5. In a line perpendicular to y=-5x+2, your slope would be 1/5. As for finding b in y=mx+b for your second equation, I would need more specific information.
Hope it helps!
