Solve the equation for y. Then find the value of Y for each value of X. y+7x=9;x=-1,0,2

y=?
x=?

(help i hate this math hw)

How many real and imaginary solutions does the equation x^2-3x=-2x-7 have?

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above
