Answer:
I can't English language better but I think this is the correct answer
Step-by-step explanation:
8x-40=x^2-2x-15
0=x^2-10x+25
0=x^2-5x-5x+25
0=x(x-5) -5(x-5)
0=(x-5)(x-5)
::x=5
If the company was in debt by 10,890.....and the debt has been reduced to 4350..
then the company payed off : 10890 - 4350 = 6540 <== so they paid off
6540.....or 6540/10890 = 60% of the debt
The correct option is option D: This is the graph of one to one function.
Function is a relationship between two sets X and Y where set X is domain and set Y is codomain.
If we draw a vertical line and it crosses the graph only once at all locations, the relation is a function and this relation will be one-one.
by checking all the options
Option A: If we draw a vertical line parallel to y-axis in this at any location then it crosses the graph only once. So it is a function with one-one relation. Therefore option A is incorrect.
Option B: Linear function is a function in which highest degree of variable is 1 and it also describes the straight line. From the graph, it is clear that it is not a straight line. Therefore option B is incorrect.
Option C: If we draw a vertical line parallel to y-axis in this at any location then it crosses the graph only once. So, it is surely a function. Therefore option C is incorrect.
Option D: If we draw a vertical line parallel to y-axis in this at any location then it crosses the graph only once. So, it is surely a one-one function. Therefore option D is correct.
The correct option is option D: This is the graph of one-to-one function.

Answer:
The one on the bottom: d^-1(x)=1/2*x +2
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
If I had to make a choice it would be C. Its strange because all numbers can be divided by 4 so they all can make a square. But the closest was C.
