Answer:
y = (x+3)^2 -1
Step-by-step explanation:
The vertex form of the equation is
y = a(x-h)^2 +k where (h,k) is the vertex
The vertex is (-3,-1)
y = a(x- -3)^2 -1
y = a(x+3)^2 -1
Pick another point (-2,0) and substitute it into the equation
0 = a(-2+3)^2 -1 to find a
0 =a(1)^2 -1
0 = a-1
1 = a
y = (x+3)^2 -1
The answer is 16
-16 is not greater than 12
Answer:
52
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then revenue was ...
9.40a +5.40(151 -a) = $1023.40
4.00a + 815.40 = 1023.40
a = (1023.40 -815.40)/4.00 = 208/4 . . . . . subtract 815.40, divide by 4
a = 52
52 adult tickets were sold that day.
Answer:
x=0.6
Step-by-step explanation:
11+4+x=x+9
15+x=x+9
15x=9x
9/9=1
9/15=0.6
x=0.6
