Answer:
(-2,-3) and (3,2)
Step-by-step explanation:
sub in x-1 into y
x^2 + (x-1)^2 = 13
x^2 + (x-1)(x-1)=13
x^2 + x^2 -2x +1 = 13
2x^2 -2x-12=0
solve for x by factoring (quadratic formula, product sum etc..)
x= -2 and 3
plug in those values into y=x-1 and solve for y
 
        
                    
             
        
        
        
4/5+3/5 = 7/5 = 1.4
3.5X5 = 17.5
1.4 + 17.5 = 18.9 = 18 9/10
