Answer:
Step-by-step explanation:
Coordinates of point B = (8, -6)
<u>Reflection across the x-axis results in:</u>
<u>Coordinates of B'</u>
- (8, -6) → (8, -(-6)) = (8, 6)
Answer:
alright
Step-by-step explanation:
Answer:no
Step-by-step explanation:
Line 1:
Expanding the vertex form, we have
x² + 2·1.5x + 1.5² - 0.25 = x² +3x +2
Expanding the factored form, we have
x² +(1+2)x +1·2 = x² +3x +2
Comparing these to x² +3x +2, we find ...
• the three expressions are equivalent on Line 1
Line 2:
Expanding the vertex form, we have
x² +2·2.5x +2.5² +6.25 = x² +5x +12.5
Expanding the factored form, we have
x² +(2+3)x +2·3 = x² +5x +6
Comparing these to x² +5x +6, we find ...
• the three expressions are NOT equivalent on Line 2
The appropriate choice is
Line 1 only
