Answer:
{y | y = –7, –1, 0, 9}
Choice B is correct
Step-by-step explanation:
The range of a function y = f(x) refers to the set of y - values for all values of x for which the function is real and defined.
The set of y values from the given table is;
–7, –1, 0, 9
Therefore, the range of the given function is;
{y | y = –7, –1, 0, 9}
Answer: 13 (and Sally will always be 3 years older than Jill)
Step-by-step explanation:
Let S and J stand for Sally and Jill's ages. We are told:
- (S-5) = (J-5)+3 [Sally is 3 years older than Jill was <u>5 years ago</u>] The 5 years ago is the reason for the (S-5) and (J-5) expressions.
If Jill is 10, how old is Sally?
(S-5) = (J-5)+3
(S-5) = (10-5)+3
S-5 = 8
S = 13
We actually don't really need an equation for solving this, other than the question asks us to write one. It doesn't matter how many years later, since Sally is 3 years older, she will always remain 3 years older, if we ignore the likelihood that the statement doesn't hold true for the period between their actual birthdays.

Answer:
5
Step-by-step explanation:
The left side simplifies to ...
2x +16
The right side simplifies to ...
2x +21 -__
The x-terms are already equal. To make the constant terms equal, we want ...
16 = 21 -__
The blank must be filled with the value 21-16 = 5 to make the statement true.
5 goes in the blank.
