7x^2 - 12 = 0
7x^2 = 12 | : 7
x^2 = 12/7 | sqrt
x = sqrt(12/7)
x = sqrt(84) / 7
x = 2sqrt(21) / 7

Answer:
C. C = 0.75b + 3.78
Step-by-step explanation:
We know that Kalvin sells bottles of water, in which he charges 75 cents for each one, with an additional 3.78 for ice.
Easily enough, we know that 0.75 has to be with a variable, because there is 75 cents being charged "per bottle." Therefore look for an answers that has the expression "0.75b".
This would leave us with "C."
1 kilometers=1000 meters
2 kilometers= 2*1000=2000
8 kilometers= 8*1000=8000
12 kilometers=12*1000=12000
The axis of symmetry is X=-2
The vertex is (-2,4)
The maximum is 4
There is no minimum as the maximum is also the vertex of the parabola.
The zeros are (-4,0) and (0,0) or just 0 and -4
The domain is all real numbers from negative infinity to positive infinity
The range contains all real numbers less than or equal to 4 :)
