Answer:
B. Quadrant 1
Step-by-step explanation:
Dilation about the origin multiplies each coordinate by the dilation factor. If the dilation factor is positive, the signs of the coordinates are unchanged, so the point they specify remains in the same quadrant.
If the dilation factor is negative, the point is reflected across the origin at the same time it is subject to dilation. That is, both coordinate signs are changed.
For a dilation factor of -2, the point L becomes ...
L(-2, -3) ⇒ L' = -2L = L'(4, 6) . . . . . in quadrant I
ANSWER
The circumcenter is (2,1)
EXPLANATION
The midpoint of BC is (-3,2)
The equation of the perpendicular bisector of BC is x=2
The midpoint of AB is (-1,1)
The midpoint of AB is (-1,1)
The perpendicular bisector of AB is y=1.
These two lines intersect at (2,1).
The point of intersection of the perpendicular bisectors of a triangle is called the circumcenter of the triangle.
Answer:
The correct option is (A).
Step-by-step explanation:
The expression Carey is solving is:
Simplify the expression as follows:
So, in Carey's calculation the third step is incorrect.
Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.
Thus, the correct option is (A).
