Answer:

Step-by-step explanation:

George: x

Alex: x + 12

Carl: 3(x+12)

3x+36+x+x+12= 68

5x + 48 = 68

5x = 20

x = 4; George's age

4 + 12 = 16; Alex's age

3(4+12)= 3(16)= 48; Carl's age

George to Alex: 4:16 = 1:4

Alex to Carl: 16:48= 1:3

George to Carl 4:48= 1:12

Carl to Alex: 48:16 = 3:1

A line has y intercept -6 and a x-intercept - 12. what is the equation of the line

koban [17]

Answer:

$\boxed{y = -\dfrac{1}{2}x-6}}$

Step-by-step explanation:

The equation for a straight line is

y = mx + b

where m is the slope of the line and b is the y-intercept.

The line passes through the points (-12, 0) and (0, 6)

(a) Calculate the slope of the line

$\begin{array}{rcl}m & =&\dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\ & = &\dfrac{6 - 0 }{0 - (-12)}\\\\& = &\dfrac{6}{-12}\\\\& = & -\dfrac{1}{2}\\\end{array}$
