Answer:
(6, 7)
Step-by-step explanation:
rotating a shape 180 degrees will create the same shape, with similar coordinates. Therefore, drawing a straight line through the origin, would make the coordinates of J (6, 7)

Answer:
x = ± 
Step-by-step explanation:
9x² - 4 = 0 ( add 4 to both sides )
9x² = 4 ( divide both sides by 9 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
= ±
Answer:
(7, -3)
Step-by-step explanation:
9x - 3y = 54
9x +1 ly = 12
Subtract both expresion
-3y - 11y = 54 - 12
-14y = 42
y = 42/-14
y = -3
Substitute y = -3 into 1;
From 1, 9x - 3y = 54
9x - 3(-3) = 54
9x - 9 = 54
9x = 54 + 9
9x = 63
x = 63/9
x = 7
Hence the solution to the system of equation is (7, -3)
