If a figure located at T(-3, -1), U(1, -2), V(2, 2), W(-1, 1) and is rotated 90∘ counterclockwise rotation about the origin, whi
ch point would be the correct location of T'?
(a) (2, 1)
(b) (-1, -1)
(c) (1, -3)
(d) (-2, 2)
1 answer:

Answer:
x=16 y=38
Step-by-step explanation:
x+y=54.......equation 1
x=y-22........ equation 2
substitute
y-22+y=54
2y-22=54
2y=54+22
2y=76
y=76/2
y=38''
x=y-22
x=38-22
x=16''

Elements of the same group in the Periodic Table will have similar chemical and physical properties.
3/3=1 and 7/8 is < 1 so 3/3 is bigger
54/4 = 13.5
take the 2 whole numbers below 13.5 and the 2 whole numbers above 13.5
12 + 13 + 14 + 15 = 54
