Answer:
Triangle M'L'Q' was dilated by a scale factor of 3
Step-by-step explanation:
Well, 4 times 3 is 12 and 7 times 3 is 21, so that means the new triangle was dilated by a scale factor of 3.
Answer: 11 units
Step-by-step explanation:
Given: On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(5, 2).
To find : length of Side RT of the polygon.
Using distance formula to find distance between (a,b) and (c,d):
Length of RT =
hence, the length of RT = 11 units.
Answer:
(2, 1 )
Step-by-step explanation:
Using the Section formula
For endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n
Then coordinates of point are
[ , ]
Here m = 5, n = 2, (x₁, y₁ ) = (- 3, - 9), (x₂, y₂ ) = (4, 5), thus partitioned point
= [ , ]
= [ , ]
= ( , )
= (2, 1 )
