Which set of side lengths is a Pythagorean triple? (A) 1,3,10 (B) 4,5,9 (C) 9,40,41 (D) 16,30,44

[2, 2.5)

(2.5, 3]

step-by-step explanation:

i think its these two not sure [2, 2.5)

(2.5, 3]

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
