Answer:

a) $k \approx \frac{\sqrt{3}}{3}$ , b) $\left(\frac{\sqrt{3}}{3}, \frac{1}{3} \right)$

Step-by-step explanation:

a) The constant of proportionality is:

$k = \frac{y}{x}$

$k = \tan \theta$

$k = \tan \frac{\pi}{6}$

$k \approx \frac{\sqrt{3}}{3}$

b) The ordered pair is:

$\left(\frac{\sqrt{3}}{3},\frac{\sqrt{3}}{3}\cdot \frac{\sqrt{3}}{3} \right)$

$\left(\frac{\sqrt{3}}{3}, \frac{1}{3} \right)$

Answer:

a=12 b=9

Step-by-step explanation:

u can substitute 3/4a in for b in a+b=12 since it is equal to b, giving you

a+3/4a=21

a=4/4a

4/4a+3/4a=21

7/4a=21

4/7(7/4a=21)

a=12

plug in 12 for a in either equation

b=3/4*12

b=9

(21=12+b) -12

9=b
