Answer:

X= 1.4 OR 7/5 OR 1 2/5

Step-by-step explanation:

x+4x-7=0 (First, Combine Like Terms)

5x-7=0 (Then, Add 7 to both sides)

+7 +7

5x=7 (Now, divide both sides by 5)

/5 /5

You get X= 1.4 OR 7/5 OR 1 2/5

Answer:

middle graph

Step-by-step explanation:

Soluton

The  second (middle ) graph is the only one that works.

  • First of all when you simplicity the right, you get y = x^2 - 1). That means that x does not go through 0,0. If you put x = 0 into x^ -  1 = 0, you get - 1. So on that basis alone both the first and third graphs are incorrect.
  • Second, both xs in the factors are plus, so x^2 is plus, which means the graph opens upward.
