Answer: x = 19

Step-by-step explanation:

5(-12x+3) + 6(10x + 7) = 9 - x + 3x + 10 Distribute on the left side

-60x + 15 + 60x + 42 = 9 + 2x + 10 combine like terms on the left side

57 = 9 + 2x + 10 Now combine like terms on the right side

57 = 2x + 19 Subtract 19 from both sides

-19 -19

38 = 2x Divide both sides by 2

x = 19

Write the equation of a line in slope intercept form given;<br> (6,-3), (0, 5)

olganol [36]

Answer:

$y=(-4/3)x+5$

Step-by-step explanation:

so you want to start by using y=mx+b

step one: find the slope (remember m is the slope in this)

m= $\frac{y2-y1}{x2-x1}$

m= $\frac{5+3}{0-6}$

m= $\frac{8}{-6}$

m= - $\frac{4}{3\\}$

step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.

y=mx+b

5= -4/3(0)+b

5=b

step three: rewrite y=mx+b with the values we found for m and for b

$y=(-4/3)x+5$

c.)Perpendicular line.

a.)Perpendicular line.

b.)Parallel line.

d.)Depending on how they are faced if the ends of the telephone wire meets the second one then it is perpendicular but if not then it is parallel that's if they are in different directions which they can not meet.Thank you for the question
