Answer:

Step-by-step explanation:
we need to find the equation of the parabola with vertex (-5,3), with axis parallel to the x-axis.
general equation of horizontal parabola is

where (h,k) is the vertex
(-5,3) is the vertex. h=-5 and k=3. plug in the values in the general equation

Now find out the value of 'a' using x intercept (4,0)



Add 5 on both sides

a=1
the equation becomes

Answer:
b ) a^7/b^6 is the correct answer
It would be at rate of 68 ill use per minute so
68x=1y
