The transformation was a 180° rotation about the origin.
Because, if we take formulas of rotation about the origin:
X1=x*cos£+y*sin£.
Y1=-x*sin£+y*cis£.
And £=180°
Than we recieve
x1=-x
y1=-y
Answer:
131/4
Step-by-step explanation:
you multiply the denominator by 32 (which is 4) and you add it to the numerator)
32 x 4 = 128
128 + 3 = 131
so your answer is 131/4
and your the answer for your equation 32 3/4 - 12 1/2
32 3/4 − 12 1/2
= 131/4 − 25/2
= 81/4
= 20 1/4
