Answer:

1) $\sqrt{9}$ and $\sqrt{16}$ (between 3 and 4)

Explanation: $\sqrt{9}$ and $\sqrt{16}$ are the closest WHOLE squares root to $\sqrt{12}$ ; any other square roots wouldn't give us a whole number, or they're farther away from

2) $-\sqrt{144}$ and $-\sqrt{169}$ (between -(12) and -(13))

3) $-\sqrt{36}$ and $-\sqrt{49}$ (between -(6) and -(7))

The slope of Consider the line whose equation is 3x + y - 3 = 0. The slope of any line that is parallel to this line is any line

PSYCHO15rus [73]

Answer:

parallel : y = -3x + 3

perpendicular : y = 1/3x + 3

Step-by-step explanation:

rewrite 3x + y - 3 = 0

y = -3x + 3

parallel has the same slope

parallel : y = -3x + 3

perpendicular is negative reciprocal of the slope

-3x becomes 1/3x

perpendicular : y = 1/3x + 3
