Answer:

D. $\frac{10}{15}$ and $\frac{14}{21}$

Step-by-step explanation:

Proportional ratios are ratios that represent the same relationship. One way to check this is to reduce the ratios, because if they are proportional, they will equal the same thing. Both $\frac{10}{15}$ and $\frac{14}{21}$ simplify to $\frac{2}{3}$ .

Hope this helps!!

<h3>You have the correct answer</h3><h3>Interest rate = 21.5%</h3>

===============================================

Work Shown:

i = P*r*t .... simple interest formula

i = simple interest

i = 2075-1000 = 1075

P = 1000 = amount borrowed (principal)

r = unknown interest rate

t = 5 = time in years

So,

i = P*r*t

1075 = 1000*r*5

1075 = 5000r

5000r = 1075

r = 1075/5000

r = 0.215

r = 21.5%

What is the constant of vanation,<br>of the line y = for through (3.18) and (5,30)?

Naily [24]

the constant of variation or namely its slope will be

$\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{18})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{30}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{30-18}{5-3}\implies \cfrac{12}{2}\implies 6$
