Answer 1

for number 1 its radical 2

Answer 2

for number #2 I think each equation has 2 solutions

Answer 3

Can you please show me how you got the first one? thank you !

Answer 4

plug in radical 2 for y and solve for x then once you find x value then check your work by multiplying the x value and radical 2 which is the y value

Answer 5

if you get 4 then the answer is right

Answer 6

in the second one \(y^2=x+4\) so you have
\[x^2+x+4=4\] and you can solve that
i believe there are two solutions

Answer 7

thank you so much!!
