Answer 1

the second equation is not clear. can you use the Equation button below the reply box and retype the second equation

Answer 2

1 divided by 32 times x squared

Answer 3

the times looks like x. use * instead.

Answer 4

x^2 +4y^2 = 100 (1)
y = x^2/32 (2)
cross multiply (2)
32y = x^2
put x^2 = 32y in (1)
32y + 4y^2 = 100
4y^2 + 32y - 100 = 0
divide each term by 4
y^2 + 8y - 25 = 0
solve the quadratic equation.

Answer 5

do you know how to solve quadratic equation?

Answer 6

Use this formula to solve for y: \[\Large \frac{ -b \pm \sqrt{b ^{2} - 4ac} }{ 2a }\]

Answer 7

yes.

Answer 8

+2.4 is correct.

Answer 9

so plugging that into the first equation I get 8.7,2.4

Answer 10

yes.

Answer 11

but your negative y above was wrong.

Answer 12

yes.

Answer 13

Yes. Coefficients of x^2 and y^2 have opposite signs and that means it is a hyperbola.

Answer 14

you are welcome. you too. :)
