Answer:
The answer is A
Step-by-step explanation:
The reason A is correct is because all of the other transformations change the size of the triangle, and A is the only answer that only reflects the image over the y axis without changing it, thus making it similar to the preimage
The = sign
1 11/20 = 31/20 = 1.55 and 1.55 =1.55
y=-2(x+2)
plug in(-2,0) into y-y1=m(x-x1)
y=m(x+2)
slope =m=-2
Yes
each pack costs 2.5, she bought x packs
x=2+4+3=9
she bought 9 packs
so 2.5 times 9=22.50
she spend $22.50
