(2/3)(30)=20
30+20=50=(x/5)
(50*5)=x=250
hope this helps
The answer would be 25/54
The vertex form of the function gives the vertex as (-6,48). The vertex of f(x)=x^2 is (0,0) so from this information, the vertex is moved LEFT 6 and UP 48. This cancels out two options. The coefficient -3 tells us that the graph is flipped or reflected over the x-axis (negative sign flips graph) and that all y-values will be 3 times as large. Larger y-values for the same x inputs makes the graph narrower.
512=2w^2 is the best answer
3 3/4 divided by 1/2 is 7 1/2.
