Five less than 1/3 a number n is 3.

$\frac{1}{3}n-5=3$

Four more than twice a number x (2x+4) is greater than (>) the sum of three and a negative seven (3-7)

2x+4>3+(-7)

Please help this is for math....

Gnesinka [82]

So here you want to show all values greater than the parabola shown. The following parabola can be found by looking at the x intercepts. Here you have x=-3 and x=2. So your parabola can be defined as y=(x+3)(x-2) because when you make those two equal to zero you get x=-3 and x=2. And so then you go ahead and do the FOIL method for both of them when you multiply and you get

y=x²-2x+3x-6 which is

y=x²+x-6

Because the parabola is shaded above, it indicates that all the values greater than y are shaded and it’s with a solid line, therefore your answer for this inequality would be choice B. I hope this helps!!
