Answer:
Step-by-step explanation:
Not A because:
(Subtract 11 from both sides)
4n > -20
(Divide both sides by 4)
n > -5
Because we have found that dividing the negative number by 4 does not work, we know B is also wrong.
Not C because:
(Subtract 11 from both sides)
-4n < -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n > 5
So, it must be D!
Here's why:
(Subtract 11 from both sides)
-4n > -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n < 5
Hope this helps!
Answer:
The Geometric Mean of 4 and 12 is 6.9
Step-by-step explanation:
Given Numbers are 4 and 12
To find : Geometric mean of the given No.
The Geometric Mean is a type of average where we multiply the nos. together and then take a square root (for two nos), cube root (for three nos) etc.
Formula for Geometric Mean is given by,
⇒ Geometric Mean of 4 and 12 =
=
=
= 6.92820323028
= 6.9
Therefore, The Geometric Mean of 4 and 12 is 6.9
Answer:
0.5
Step-by-step explanation:
6/13 is the same as saying 6 ÷ 13
6 ÷ 13 = 0.4615384615
The first position after the decimal is the tenths column. Round up, because 6>5.
The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope that is undefined, and the graph of x = 1/6 is a vertical line with a slope of 0.
The lines are perpendicular to each other because the graph of y = –6 is a vertical line with a slope that is undefined, and the graph of x =1/6 is a horizontal line with a slope of 0.
