Answer:

Step-by-step explanation:
The first equation is 
The second equation is 
When we graph these two equations, <em>they will meet at a point which represent the solution of the two equations</em>.
We can solve the two equations simultaneously to determine their point of intersection.
Let us substitute the second equation into the first equation to get;

Multiply through by 2 to get;

Group similar terms to obtain;

Simplify;

Divide both sides by 3;

Put
into the second equation;



Therefore the graphs of the two functions intersect at (2,3)

Answer:
C. 1 solution
Step-by-step explanation:
I calculated logically
Hello,
y=x²-x-2=x²-2*1/2*x+1/4-2-1/4=(x-1/2)²-9/4
1. Vertex=(1/2,-9/4)
2. if x=0 then y=0²-0-2=-2
3.The roots:
x²-x-2=0
==>(x-1/2)²-9/4=0
==>(x-1/2-3/2)(x-1/2+3/2)=0
==>(x-2)(x+1)=0
x=2 or x=-1
4. axe of symmetry: x=1/2
