The correct answer is D.
This is because a converse statement switches the places of the hypothesis and conclusion.
-4x + 9y = 9...............(1)
x - 3y = -6 Multiply through by 3:-
3x - 9y = -18..............(2)
adding equations (1) and (3):-
-x = -9
x = 9
Substitute for x in equation (1)
-4(9) + 9y = 9
-36 + 9y = 9
9y = 45
y = 5
Answer is x = 9 and y = 5
X = 5 and y = -12 is in the fourth quadrant. Hypotenuse = 13
sin theta = opposite / hypotenuse = -12 /13

The interquartile range (IQR) is a measure of inconstancy, in light of partitioning an informational collection into quartiles. Quartiles isolate a rank-requested informational collection into four a balance of. The qualities that gap each part are known as the primary, second, and third quartiles; and they are signified by Q1, Q2, and Q3, individually.
Where as, measures of spread portray how comparable or changed the arrangement of watched esteems are for a specific variable (information thing). Measures of spread incorporate the range, quartiles and the interquartile range, difference and standard deviation.
