B

Step-by-step explanation:

If you factor B you get:

y =

The points where the graph crosses the y axis are the x-intercept, meaning that y = 0 there.

Therefore:

x^2 + 3 can't be equal to zero because the square root of a negative number does not exist. Therefore, the only zero is x = 7 so it only crosses the x-axis in one place.

You can check the others the same way by factoring, but this is the only one with a single solution.

it has the same slope and a different y-intercept

hope this : )

9 sandwiches per hour

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
