Answer: 16
Step-by-step explanation:

Let's complete the square.



Answer:
X=Y
Step-by-step explanation:
5x-5Y=
+5y=5y
5x=5y
divide both sides by 5
x=y
The domain is

and the range is

Domain is x values (horizontal axis), while range is y values (vertical axis). On a line like this one, domain is calculated from the left most point to the right most, while range is calculated from the down most to the upmost.
Because this line is a solid line rather than a dotted line, less than or equal to

signs are used rather than just

less than signs.
The correct answer is 48%
There are 10 even numbers from 1 to 21.
That makes the probability of an even number 10 out 21.
10 / 21 x 100 = 48%
Option C (Same as Option D)
<h2>
Explanation:</h2>
Option C and D are the same, so I'll assume you made a mistake when writing this question. However, let's figure out which of the following equations has a slope of -2 and passes through the point (2,3):
A. y = -2x + 6
B. y - 3 = -2(x + 2)
C. y = -2x + 7
<em />
<em>All these equations have a slope of -2.</em>
FROM OPTION A:

Since
then the line doesn't pass through the point (2, 3)
FROM OPTION B:

Since
then the line doesn't pass through the point (2, 3)
FROM OPTION C:

Since
then the line passes through the point (2, 3)
<em>Finally, the equation that has a slope of -2 and passes through the point (2,3) is Option C (Same as Option D)</em>
