Let the numbers be x and y
x= y-2.... (1)
and, 2y = 16 + 4x.... (2)
putting the value of x from (1) in (2),
2y = 16 + 4x
=> 2y = 16 + 4(y-2)
=> 2y = 16 + 4y - 8
=> 2y = 8 + 4y
=> 2y - 4y = 8
=> -2y = 8
=> y =-8/2
=> y= -4
and x = -4-2 = -6
hence , in short the numbers are -2 and -4
Answer:
Step-by-step explanation:
Using the equation of line
y - y_1 = m(x - x_1)
y = mx + C
First first the slope of the equation
y = 9x - 4
Note: if two lines are perpendicular, their slope will be negative reciprocal
Slope = 9, but because it is perpendicular
m = -1/9
Using the equation
y - y_1 = m(x - x_1)
With the point (-9,-17)
x_1 = -9
y_1 = -17
y - (-17) = -1/9(x - (-9)
y + 17 = -1/9(x + 9)
y = -1/9(x + 9) - 17
Open the bracket.
y = (-x -9)/9 - 17
Lcm is 9
y = -x -9 - 153 / 9
y = -x - 162 / 9
Let's separate
y = -x/9 - 162/9
y = -x/9 - 18
y = -1/9x - 18
Therefore, the equation of the line is y = -1/9x - 18
Ascending order :-
10.5 , 11 , 11.5 , 14.5 , 17 , 17 , 18 , 19
Median,
={(n/2)th + (n/2 +1)th}/2
={(4)th + (5)th}/2
=(31.5)/2
=15.75
I.Q.R.,
Median of lower half,
={(n/2)th + (n/2 +1)th}/2
={(2)th + (3)th}/2
=(22.5)/2
= 11.25
Median of upper half,
={(n/2)th + (n/2 +1)th}/2
={(2)th + (3)th}/2
=35/2
=17.5
I.Q.R. = 17.5 - 11.25 = 6.25
