M∠LON = 7x-92 and m∠MON = 6x+12

Tomtit [17]

Answer:

$M∠LOM = \boxed{48}$

Step-by-step explanation:

$M∠LOM + m∠MON = 180 \\ 7x-92 + 6x+12 = 180 \\ 13x - 80 = 180 \\ 13x = 180 + 80 \\ 13x = 260 \\ \boxed{ x = 20} \\ (7x - 92 )= 140 - 92 = \boxed{48} \\$

What are the slope and y intercept of the line described by the equation y=-4/5x -10

rodikova [14]

The slope is $-\frac{4}{5}$ and y-intercept is -10

Step-by-step explanation:

Given equation is:

$y = -\frac{4}{5}x-10$

The given equation is in slope-intercept form

General form of slope-intercept form of equation of line is:

$y = mx+b$

Here

m is the slope

b is the y-intercept

So,

comparing both equation we get

The coefficients of x

$m = -\frac{4}{5}$

And

$b = -10$

Hence,

The slope is $-\frac{4}{5}$ and y-intercept is -10
