MAXImum [283]3 years ago
4 0

Answer:

C and E

Step-by-step explanation:

We are given that

x_1=0.2,y_1=0.3

\frac{y}{x}=\frac{0.3}{0.2}=\frac{3}{2}

k=\frac{y}{x}=\frac{3}{2}

A.x_2=1.2,y_2=2.3

\frac{y_2}{x_2}=\frac{2.3}{1.2}=\frac{23}{12}\neq=\frac{3}{2}

Hence, it is not in proportional relationship with (0.2,0.3)

B.(2.7,4.3)

x_3=2.7,y_3=4.3

\frac{y_3}{x_3}=\frac{4.3}{2.7}=\frac{43}{27}\neq\frac{3}{2}

Hence, it is not in proportional relationship with (0.2,0.3).

C.(3.2,4.8)

x_4=3.2,y_4=4.8

\frac{y_4}{x_4}=\frac{4.8}{3.2}=\frac{3}{2}

Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).

D.(3.5,5.3)

\frac{y_5}{x_5}=\frac{5.3}{3.5}=\frac{53}{35}\neq \frac{3}{2}

Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).

E.(5.2,7.8)

\frac{y_6}{x_6}=\frac{7.8}{5.2}=\frac{3}{2}

Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).

pishuonlain [190]

Answer: $7800 was invested at 9%

$5900 was invested at 3%

Step-by-step explanation:

Let x represent the amount invested in the fund that paid a dividend of 9%.

Let y represent the amount invested in the fund that paid a dividend of 3%.

Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you received a total of $879. This means that

0.09x + 0.03y = 879- - - - - - - - - 1

This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $839. It means that

0.1x + 0.01y = 839 - - - - - - - - - -2

Multiplying equation 1 by 0.1 and equation 2 by 0.09, it becomes

0.009x + 0.003y = 87.9

0.009x + 0.0009y = 75.51

Subtracting, it becomes

0.0021y = 12.39

y = 12.39/0.0021

y = 5900

Substituting y = 5900 into equation 1, it becomes

0.09x + 0.03 × 5900 = 879

0.09x + 177 = 879

0.09x = 879 - 177

0.09x = 702

x = 702/0.09

x = 7800
