1.6 is in between those 2 numbers
Judging by the problem you want me to use substitute method
Since why equals 1/2x-1 you
Do 2(1/2x-1)= x-2
You multiple by 2 cause there’s two on the top for y. So the problem is now 4x-x-2
Combine like terms 3x+2=14
Subtract two on both sides
3x=12
X=4
Go back to the bottom since u know x now do y= 4.1/2-1 solve to get one
Y=1 so your answer is (4,1)
9(v+2)
When you factor you are essentially dividing by 9 when you take it out and add parenthesis
I believe the answer is
7x^3-2x^2-5
