Answer:

x = 21

Step-by-step explanation:

7x - 3 + 2x - 6 = 180 {Linear pair}

7x + 2x - 3 -6 = 180 {combine like terms}

9x - 9 = 180

9x = 180+ 9

9x = 189

x = 189/9

x = 21

Is x=4 and y=5 perpendicular

faltersainse [42]

True!

<h2>Explanation:</h2>

The Cartesian coordinate system is formed by two perpendicular axes, which are the x-axis and y-axis. In this problem, we are given two lines:

$x=4 \ and \ y=5$

The line $x=4$ is parallel to the y-axis and has an undefined slope.
The line $y=5$ is parallel to the x-axis and has a slope of zero.

Since the x and y-axes are perpendicular, then the lines $x=4 \ and \ y=5$ are also perpendicular.
