Answer:
x = - 7.23
Step-by-step explanation:
3(x+6)= -3.68 Start with the breackets.
3x + 18 = - 3.69 Subtract 18 from both sides
3x = - 3.69 - 18
3x = -21.69 Divide by 3
x = - 21.69/3
x = -7.23

Answer:
y = (x -1)² -16
Step-by-step explanation:
Note the location of the vertex (point A) on the graph. Its x-coordinate is readily identifiable as 1. Its y-coordinate is some value between -15 and -20, closer to -15. (If you go to the trouble of finding the vertex coordinates, you discover they are (1, -16).)
Once you have determined what the vertex is, you can compare the offered answer choices to the vertex form ...
y = (x -h)² +k
where (h, k) are the vertex coordinates. That is, you are looking for an answer choice that is something like ...
y = (x -1)² -16
Well you multiply 234 and 4 = 936. so X = 936.
