Answer:
41.25
Step-by-step explanation:
0.70 + 1 (40.55) = 41.25
The point will be 1/4 of the distance along the line hence cutting it into 1/4 : 3/4
-1 + (7 - -1)/4 = -1 + 2 = 1
-10 + (6 - -10)/4 = -10 + 4 = -6
The point is at (1 , -6)
Answer:
For Question Number 3 :
Option 2 is correct as x is 6 units left means it has been subtracted by 6 units, it becomes x-6 and y is 6 units down it means it has also been subtracted by 6 units which becomes y-6.
For Question Number 4 : The correct answer is option 3.
Step-by-step explanation: As the reflection is along the line y=1, it simply means that x coordinate will remain constant which is 3. Now as the point is (3,10) which means it is 9 units up the line y=1 and so it will be down 9 units from the line y=1. As the law of reflection says that it has to be same on both the sides. hence 9 units down from the line y=1 means y=-8. So coordinate of the reflection of that point becomes (3,-8).
For Question Number 5 : The given vertices are P(4,1),Q(2,-8) and R(-8,1)
Now reflection along Y Axis , P' becomes (-4,1)
Q' becomes (-2,-8) and R' becomes (8,1). hence these are the new vertices of the triangle.Option 2 is the correct option.
