Answer: Is this completing a a square?
Step-by-step explanation:
9x - 8y = -11
-9x + 3y = 21
Add the second equation
9x - 8y = -11
+ (-9x) + 3y = 21
-5y = 10
divide both sides by -5
y = -2
substitute y into one of the two equations in the beginning
9x - 8(-2) = -11
9x + 16 = -11
subtract 16 on both sides
9x = -27
divide both sides by 9
x = -3
The answer is (-3, -2)
x = -3
y = -2
For number 9 just take the two functions and multiply or add them I can’t tell what sign that is

Answer:
right by 3 units
because....
f(x)=(x-1)², g(x)=(x+2)²
f(0)=(0-1)²= 1
g(0)=(0+2)²= 4
Both graphs get non-negative value, so no up or down translation
g(x) gets greater value than f(x) and its zero is shifted right by 4-1= 3 points, so we can say translation is right by 3 units
