Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
The discriminant is 385.
Yes
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
If y = 2x+1 is a tangent line to the circle 5y^2 +5x^2 = 1 then the point of contact is at (-2/5, 1/5) because it has equal roots

Yes
5x2+500 = 844.45 5x2 = 844.45-500 5x2 = 344.45 x2 = 344.45/5 x2 = 68.89 x = the square root of 68.89 = 8.3 x = 8.3

False

6x2-2x+36 = 5x2+10x 6x2-5x2-2x-10x+36 = 0 x2-12x+36 = 0 (x-6)(x-6) = 0 x = 6 or x = 6 It has two equal roots.
Two. x = + i sqrt(8.4) x = - i sqrt(8.4)
5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3
5x2+7x = 12 5x2+7x-12 = 0 (5x+12)(x-1) = 0 x = -12/5 or x = 1
5x2 + 9x + 4 = (x + 1)(5x + 4).
