The answer for the first question: C The rotated image may be larger than the original image.
Answer:
answer below
Step-by-step explanation:
ABCDE go through dilation over center (6 , -2) with factor of 1/2 to FGHIJ
AB // FG slope: -2 , √20:√5 = 2: 1
BC // GH // X axis 8:4 = 2:1
CD // HI, slope= 1 , √8:√2 = 2:1
DE // IJ // x axis, 4:2 = 2:1
EA // JF // y axis, 2:1
16/12 = (x-1)/6
x-1 = 4/3 . 6
x = 24/3 + 1 = 9
32/24 = (y+1)/21
y+1 = 4/3 . 21
y = 84/3 - 1 = 25
Vertical angles are always equal. The vertical angles are the ones opposite each other. Therefore x would equal 40.
Answer:
Step-by-step explanation:
(-9/6) / (3/-2) ; reciprocal of -3/2 = - 2/3
so
(-9/6) * (-2/3)
= 18/18 (negative times negative equals positive)
= 1
