Question

If y is directly proportional to x and y = 24 when
x = 10, then find:
(a) the constant of proportionality.
(b) the value of y when x = 24.
(c) the value of x when y = 90.​

Answer 1

Answer:

2.4 is constant of proportionality  with assumptions

otherwise data is not sufficient to get constant of proportionality

Step-by-step explanation:

Y ∝ aX + b

for x = 10

24 = 10a + b

if we assume that b = 0

then

24 = 10a

a = 2.4

2.4 is constant of proportionality  if b = 0

otherwise data is not sufficient to get constant of proportionality

Answer 2

Answer:

constant of proportional
