10,000,000+2,000,000+400,000+30,000+0,000+000+00+0=12,430,000

**Answer:**

121 – 1 = 120. 120 – 3 = 117.

**Step-by-step explanation:**

**The two numbers that would multiply to equal the value on top and add to the value on the bottom would be -2 and 9.**

**-2 x 9 = 18 **

**-2 + 9 = 7**

Answer:Graph 4

Step-by-step explanation:

To find a function is one to one we have to perform vertical and horizontal line test

And if it clears the test then it would be one to one

Graph 1 doesn't clears horizontal line test as if we draw a horizontal line it will cut the curve two times with same value of Y

Same is the case with Graph 2 , as if we draw a horizontal line it will cut the graph at two same values!

So graph2 also eliminated!

Graph 3 is an ellipse along y axis so it so the horizontal line cuts the ellipse two times with same values of y and if we draw a vertical line then, also it will cut the ellipse two times with same value of x

So option 3 eliminated!

But in Graph 4 if we draw a horizontal or vertical line it will cut the given points with same value of y or x

So, Graph 4 represents one to one function.

Hope it helps!!!
