If the graph of $2x+ky=10k$ intersects $X$-axis at $(2, 0)$, then $k$ is

If $x^2+\frac{1}{x^2}=27$, then the value of $\left(x+\frac{1}{x}\right)$ is

Is the point $(0, 3)$ lies on the line $3x+4y=12$?

The angles of a triangle are $5(y-1)°, 3(2y-5)°$ and $9y°$. Find $y$ and assign the name of the triangle.

Factorise $x^3+3x^2+3x+1$.

Draw the graph of linear equation in cartesian plane $x-2=0$.

The point $(2, 3)$ lies on the graph of the linear equation $3x-(a-1)y=2a-1$. If the same point also lies on the graph of the linear equation $5x+(1-2a)y=3b$, then find the value of $b$.

Draw a triangle whose sides are represented by $x=0, y=0$ and $x+y=3$ in the cartesian system. Also, find the coordinates of its vertices.
