solve each question for X , y=-9+x^2

Sagot :

y = -9 + x^2
y + 9 = -9 + 9 + x^2
y + 9 = x^2
√y+9 = √x^2
√y+9 = x
x = √y+9

√ is the square root symbol
so basically you want to isolate only one of the variable on one side so
y=-9+x^2
add 9 to both sides
y+9=x^2
square root both sides
[tex] \sqrt{y+9}=x [/tex]

x=[tex] \sqrt{y+9} [/tex]
