Answer:
Step-by-step explanation:
r=4/(-2)=-2
8 - 11 = -3. The square root of 25/121 = (the square root of 25) / (the square root of 121) = 5/11 . -3 x 5/11 = -3/1 x 5/11 = (-3 x 5) / (1 x 11) = (-15)/11 = -15/11.
Answer:
(5.5,-8)
Step-by-step explanation:
(7 + 4)/2 = 5.5
(-6 + -10)/2 = -8

Cross multiply.
5.4x=9*25.8
5.4x=232.2 Divide both sides by 5.4
x=43
