Answer:
a.
Step-by-step explanation:
Dilation does not change the direction (slope) of any lines. The slope of the image line is the same as the original when the line is subject to dilation. The y-intercept point (0, -2) will be multiplied by the dilation factor, so will become 4(0, -2) = (0, -8). The dilated line will have equation ...
y = -1/4x -8 . . . . . matches choice A

Answer:
Real numbers are Closed under multiplication.
Irrational numbers are Not Closed under division.
Integers are Closed under subtraction.
Positive rational numbers are Closed under addition.
Step-by-step explanation:
a) The product of any two real numbers is a real number, so the set is closed.
b) In some cases, the quotient may be rational. (√18)/(√2) = 3, for example. So, the set is not closed.
c) The difference of any two integers is an integer, so the set is closed.
d) The sum of any two positive rational numbers is a postive rational number, so the set is closed.

Answer: 32 days. This is more than a month.
Step-by-step explanation:
First, convert the 30 pound bag into ounces. To do this you just need to multiply 30 by 16. You will get 480 ounces (so one bag has 480 ounces of food in it. Then, just divide that by the ounces eaten by Socks in a day. 480/15 is 32. So one bag of food lasts 32 days. At the most, one month can have 31 days in it so this bag will last for more than a month. Hope this helps!
