Step-by-step explanation:
Answer: (-2, 5/3)
explanation: since you are given x = -2, just plug that into the equation and solve.
It is A. Because .8 is the same has saying .80, it is .80>.79, and 80 is greater than 79
Ratio of their bases =
Ratio of their altitudes = 
<u>Step-by-step explanation:</u>
For first rectangle, it was given that
Base 1 = 12 inches
Altitude 1 = 6 inches
For the second rectangle, it was given that
Base 2 = 10 inches
Altitude 2 = 5 inches
Ratio of their bases is given by the ratio of the base of the first rectangle to the second one.
Ratio of their altitudes is given by the ratio of the altitude of the first rectangle to the altitude of the second rectangle.
Ratio of their bases =
Ratio of their altitudes =
