Answer:
D) y = -3
Step-by-step explanation:
3y² +2(y – 5) > 8
3y² + 2y - 10 - 8 > 0
3y² + 2y - 18 > 0
y = -3
3(-3)² + 2(-3) - 18
27 - 6 - 18
3 > 0
The slope of line "v" is
<h3><u>Solution:</u></h3>
Given that Line w and line v are perpendicular to each other
Also given that line w passes through the points ( -4, 8 ) and ( 12, -2 )
To find: slope of line v
Since line w and line v are perpendicular to each other, product of slopes of line w and line v are equal to -1
---- eqn 1
Let us first find slope of line w
<em><u>The slope "m" of a line is given as:</u></em>
Thus the slope of line "w" is
Substituting the slope of w in eqn 1 we get,
Thus the slope of line "v" is
We know that the definition of the Absolute Deviation, d at a data point is the absolute value of the difference of the value of the data point, v and the mean for the data set, m.
Thus,
In our case, v=7 and m=5
Therefore,
therefore, the Absolute Deviation is as asked in the question is 2
So, your answer to this problem is
(7y + 16)(4y - 3).
