Which sequence of transformations maps triangle abc onto triangle def.
1. a reflection over the x-axis followed by a reflection over the y axis

2. a 180 rotation about the origin followed by a reflection over the line y=x

3. a 90 degree clockwise rotation about the origin followed by a reflection over the y-axis

4. a translation 8 units to the right and one units followed by a 90 degree counterclockwise rotation about the origin

  1.  a reflection over the x-axis followed by a reflection over the y axis

Step-by-step explanation:

The sequence of corresponding vertices is CCW for both triangles, so an even number of reflections (or a rotation) is involved. (This eliminates choices 2 and 3.)

Segment AB is in the opposite direction of segment DE, so rotation by 90° cannot be involved. (This eliminates choice 4.)

Triangle DEF is apparently a rotation about the origin by 180° of triangle ABC. The equivalent is reflection across both axes. (Matches choice 1.)

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
