Answer:

p = 4,8 ; r = 7,5 ; q = 4,5

Step-by-step explanation:

according to Thales's theorem, we have:

$\frac{3}{p}=\frac{5}{5+3}=\frac{5}{8}=> p= 3:\frac{5}{8}=4,8$

and: $\frac{5}{8}=\frac{r}{12}=> r=7,5\\\\\frac{5}{3}=\frac{7,5}{q}=> q=4,5$

puteri [66]

Answer:

y = - $\frac{2}{3}$ x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )
