6x +12 - 3x = 70
6x-3x+12= 70
3x+12= 70
move +12 to the other side
sign changes from +12 to -12
3x+12-12=70-12
3x= 58
divide by 3 for both sides
3x/3=58/3
x=58/3 or x=19 1/3
Answer: x=58/3 or x=19 1/3
Answer:
3 points
Step-by-step explanation:
in a function, an x-value must have only one y-value correlated with it.
So, you would need to remove either (-3, 2) or (-3, 3)
And, you would need to remove either (2, -2) or (2, -4)
<em>And, </em>you would need to remove either (1, 4) or (1, -4)
So--you need to remove 3 points in total for this to be a function.
[a y-value can have multiple x-values. the two points at -4 are allowed, and do not need to be removed for both of them to be there]
