lutik1710 [3]
X represent the number of laps Marcy swam, 114x represent the number of times Toni swam.

20 + 0.80(114x) + 15 + 0.85x = 257
20 + 91.2x + 15 + 0.85x = 257
92.05x + 35 = 257

Required equation is 92.05x + 35 = 257

Which set of values could be from a direct proportion
mr Goodwill [35]

Answer:

First table

Step-by-step explanation:

We have to find the set of value which could be from a direct proportion.

We know that

Direct proportion :

When x is directly proportional to y

x\propto y

x=ky

Where k=Proportionality constant

k=\frac{x}{y}

K remain constant when x and y are in direct proportion

From first table

k=\frac{\frac{1}{2}}{6}=\frac{1}{12}

k=\frac{1}{12}

k=\frac{2}{24}=\frac{1}{12}

K=\frac{3}{36}=\frac{1}{12}

When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.

From second table

k=\frac{0}{0}= not ]define

k=\frac{1}{1}=1

It is not direct proportion because k does not remain constant.

From third table

k=\frac{0}{2}=0

k=\frac{2}{4}=\frac{1}{2}

It is not direct proportion because k does not remain constant.
