Question

Give the graphical representation of the following equation and also identify that the line is parallel to which axis :

A line parallel to the x - axis that passes through 4 on the y - axis.|

Please Answer with explanation

Answer 1

Answer:

Hence, the equation of a straight line parallelto x-axis at a distance b from it is y = b. The equation of x-axis is y = 0, since, x-axis is aparallel to itself at a distance 0 from it. Let P (x,y) be any point on the x-axis. Then clearly, for all position of P we shall the same ordinate 0 or, y = 0.

Answer 2

That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. So it's the engines that move a plane forward, while the wings move it upwardCalculate:

\sqrt{ 3 + 2 \sqrt{2} } + \sqrt{3 - 2 \sqrt{2} }3+22+3−22

(√2+√3)(√2−√3)

By the algebraic identity, a2−b2=(a+b)(a−b)

(√2+√3)(√2−√3)=(√2)2−(√3)2

⇒2−3=−1
