Answer:
the vertex is (1,-1)
Step-by-step explanation:
y = −3x^2 + 6x − 4
the vertex is at
h= -b/2a where ax^2 +bx+c
h= -6/2(-3)
h= -6/-6
h=1
substitute this in to find the y value
y = -3(1)^2 +6(1)-4
y = -3+6-4
y = -1
the vertex is (1,-1)

Answer:
X intercept: -8
Y intercept: 2
Step-by-step explanation:
Simplify the equation, and then solve like a normal two-step equation. (I'm sorry that it wasn't a great explanation. If you want a better one just send me an email in the inbox and I can give you a better explanation.)
Answer: 1 is correct
2 is correct
3 is correct
4 is correct
5 is correct
6 is correct
7 is correct
8 is wrong it should be because you wouldn't add you would subtract it and the other number is negative so it would be x=-26
9 is correct
10 is correct
13 is correct
14 I think is correct
I think 15 is incorrect because if he says one less than twice the number of last year then I think you first should subtract 1 from 25 and then divide by 2 this would give you 17 packages
and I think 16 is correct too.
Hope this helped
