-- Reflecting across the x-axis makes all the x-coordinates the negative of
what they were before the reflection. The y-coordinates don't change.
-- Translating 2 units up makes all the y-coordinates 2 greater than
they were before the translation. The x-coordinates don't change.
You didn't give us a list of new coordinates, so there's nothing
to match with.
Answer:
1: 7 2: 3
Step-by-step explanation:
Answer:
∠ D = 28°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ EBC is an exterior angle of Δ ABE, thus
∠ EBC = 90° + 34° = 124°
BD bisects ∠ EBC, so
∠ EBD = 124° ÷ 2 = 62° , then
∠ D = 180° - (90 + 62)° = 180° - 152° = 28° ( angle sum of triangle )
Answer:
the first one i think
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
just think logically about it.
you take f(x) (which stands for the result value y, you know that), do not change f(x) in any way but add finally 5 to every y value created.
there is no other effect than moving the whole f(x) curve up by 5 units, because every y value is now bigger by 5 units.
