Triangle ABC, with vertices A(3, 0), B(2, 4), and C(4, 2), undergoes a transformation to form triangle A′B′C′, with vertices A′(3, 0), B′(2, -4), and C′(4, -2). The type of transformation that triangle ABC undergoes is a . If triangle A′B′C′ undergoes a transformation to form triangle A″B″C″, with vertices A″(-3, 0), B″(-2, -4), and C″(-4, -2), then the type of transformation that triangle A′B′C′ undergoes is a .

I would like to add the real answer but since there are too many already I'll leave it here. The first answer is a reflection across the x axis and the second is a reflection across the y axis.

answer:

c. the third graph

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
