I-Ready Practice: Proportional Relationships - Quiz - Level G

) The equation y = 16x represents the relationship between , the number of pounds, and

y, the number of ounces.

- Which ordered pairs represent the number of pounds and the number of ounces

in the given equation? Choose ALL that apply.

(3,48)

(16,80)

(10,160)

(48,3)

(80,5)

(160,10)

Step-by-step explanation:

given the expresseon that relates the number of ounces y and number of pounds x as y = 16x

The equation is a directly proportionality with a Proportionality constant of 16.

Thus means that the value of y keeps increasing by a factor of 16 for any value of x.

The ordered pairs that represent the number of pounds and the number of ounces are;

If x = 3

y = 16(3) = 48

Hence (3, 16) is an ordered pair

also if x = 10

y = 16(10) = 160

Therefore (10, 160) is another ordered pair

Hence the correct ordered pairs are (3, 16) and (10, 160)

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the two may have that, even a breakdown is probably offered
