Hey sisters!
Step-by-step explanation:
Answer:
x= 3.47 or x= -4.47 , y= 0.53 or y= 8.47
Step-by-step explanation:
quadratic equation:
x^2 + y^2 = 16
(-b± √b^2 - 4*a*c) /2
(-1 ± √ 1-4*1*16)/2
(-1 ± 3√7)/2
(-1 ± 7.94)/2
(-1 + 7.94 )/2 or (-1-7.94)/2
x= 3.47 or -4.47
therefore:
x+y = 4
3.47 + y = 4 or -4.47 + y = 4
y = 4-3.47 or y = 4+ 4.47
y= 0.53 or y = 8.47
