Answer:
Step-by-step explanation:
Rotation by -90° about the origin is the transformation ...
(x, y) ⇒ (y, -x)
So, your pre-image points are ...
A'(6, 3) ⇒ A(3, -6)
B'(-2, 1) ⇒ B(1, 2)
C'(1, 7) ⇒ C(7, -1)
At h=1 y=-2 so -2 hope it helps!
Answer:
115
Step-by-step explanation:
Since line v and line u are parallel:
m<14 and m<13 must be alternate exterior angles and alternate exterior angles has equal measure so the answer is:
m<13 = m<14 = 115.
Answer:
Step-by-step explanation:
9. disagree;
error: he should have divided 60 by 4, not subtracted. So the correct answer is x = 15.
10. disagree;
error: it should be 3x + 2 = 127 (opposite angles)
so x = 125/3
