If you want 20 points answer these questions and make it brain list 1.)What is the mapping notation for translating point (x, y) down 3 units?
a.)(x, y−3)
b.)(x−3,y)
c.)(x, y+3)
d.)(x+3,y)
2.)What translation vector translates A(−2,7) to A′(5,−1)?
a.)(7,−8)
b.)(−7,8)
c.)(3,6)
d.)(3,−6)
3.)Which transformation maps B(2,5) to B′(−2,−5)?
a.)A 270° rotation
b.)A 180° rotation
c.)A 90° rotation
d.)Reflection about the y-axis
4.)Point (a, b) is reflected about the x-axis. The resulting point is then reflected about the y-axis to produce a final point. Which transformation maps the original point directly to the final point?
a.)A translation down b units and to the left a units
b)A 90° rotation
c.)A 180° rotation
d.)A 270° rotation

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

answer is 12345678900987654321234567890987654321

step-by-step explanation:

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
