If x =-5 then you put -5 in place of x.
y=-5+7
y=2
Answer:
X is intercepted at -7
Y is intercepted at 2
Step-by-step explanation:
(x-3)^2 + (x+5)^2=9^2
(x^2-6x+9) + (x^2+10x+25)=81
2x^2+4x+34=81
2x^2+4x-47=0
From here just use quadratic formula
Let, the number be "a"
Now, according to the question,





So, the number is 72
