What is the value of k in y = kx, if y = 12 when x = 24?

the value of k is

k = 1/2

Step-by-step explanation:

from the question y = kx,

where y = 12 and x = 24

we will first of all make k the subject of the formula

y = kx

divide both sides by the coeficient of k which is x

y/x = kx/x

y/x = k k is the constatnt of proportionality

since we are given the value of x and y , we slot it in to determine the value of k.

k = y/x

k = 12/24

k = 1/2

check if your answer is correct , put the value of k into te question and see if LHS = RHS

y = kx

12 = 1/2 × 24

12  = 24/2

12 = 12 PROVED

answer: do we write it

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
