Following order of operations you would first multiply, so 6 would replace 3*2, and then you would add the 5 to the 6 so 11 and then subtract the 2 to get the answer of 9.
-6(a+8)
= (-6)(a+8)
= (-6)(a)+(-6)(8)
Your final answer would be -6a - 48!
Times both sides by (x-2)
x+3=5(x-2)
x+3=5x-10
minus x both sides
3=4x-10
add 10 both sides
13=4x
divide by 4
13/4=x
Which set of ordered pairs represents a function? {(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)} {(3, –1), (7, 1), (–6, –1), (9, 1

A function can't have x repeating any of the same number twice for example the first one (2, -2), (1, 5), (-2, 2), (1,-3), (8,-1) you have two 1's (1,5) and (1,-3) the x is the first number. Now a function can have the same y value. So your answer is (3, -1), (7,1), (-6,-1), (9,1), and (2,-1) you have to have all different x values in order for it to be a function. Hope that helps.
