Answer:
1st, 3rd and second last one
Fist convert the equation to vertex form
y = 2(x^2 + 14x) - 8
y = 2 [(x + 7)^2 - 49] - 8
y = 2(x + 7)^2 - 106
So the vertex is at (-7,-106)
Answer:
-19-28i
Step-by-step explanation:
Simplify and write the answer in standard form, a+bi.
1 - 9
2 - 87
3 - -2
4 - -9
that’s the answers for them :), have a great day !! :)
Answer:
x = 21.3 repeating. so put the - on top of the 3 if you're writing it down
