Answer:

x=30/7

Step-by-step explanation:

7x+12+3x=-6(x-7)+9x

10x+12=-6x+42+9x

10x+12=3x+42

10x-3x+12=42

7x+12=42

7x=42-12

7x=30

x=30/7

A line with a slope of 0 passes through the point (6, 16). What is its equation in slope-intercept form?

satela [25.4K]

Answer:

y = 0x + 16

Step-by-step explanation:

Slope of line m = 0

$(6,\:16)=(x_1,\:y_1)$

Equation of line in slope point slope form is given as:

$y-y_1 = m(x-x_1) \\\\\therefore y - 16 = 0(x - 6)\\\\\therefore y - 16 = 0x - 0\\\\\therefore y = 0x + 16\\\\$

This is the required equation in slope intercept form.
