Answer:
2 right, 4 down, y-axis
Step-by-step explanation:
Reflection across the y-axis changes the left-right orientation. Reflection across the x-axis changes the up-down orientation. Translation before the reflection can put the figure in a place so that the reflection gives its final location. Translation does not affect the orientation.
__
We observe that the north-south wall is on the west side of the building at Site A, and on the right side at Site B. That means the orientation was changed left-to-right, so reflection was across the y-axis.
If the reflection occurred last, then the position before reflection must have the northeast corner moved from (-3, 5) to (-1, 1). That is, the x-coordinate is increased by 2, and the y-coordinate was decreased by 4.
The building at site A was translated <u><em> 2 </em></u> units right and <u><em> 4 </em></u> units down; then it was reflected across the <u><em> y-axis </em></u>.
Answer:
Y=1/2x-3
Step-by-step explanation:
Answer:
c = 1
Step-by-step explanation:
Given
x² + 2x + c
To complete the square
add ( half the coefficient of the x- term )² to x² + 2x
x² + 2(1)x + 1
= (x + 1)²
Thus
x² + 2x + 1 = (x + 1)² ← a perfect square
with c = 1
Answer:
2800 divided by 64 equals 43.75 Your welcome :)
Step-by-step explanation:
Rowan raised 640 last year
this year he raised 15% more
percent means parts out of 100
15%=15/100=3/20
15% of 640
'of' can be translated as multiply
15%=3/20
3/20 times 640=1920/20=192/2=96
this is 15%
he raised 15% MORE SO
640+96=this year=736
he raised 736 dollars this year
