If y=80 when X =8 what is the value of y when x=12

y=120

Step-by-step explanation:

y=80 when ×=8 because 8 × 10 = 80

therefore multiplying 12 by 10 gives us 120

y=120 when x=12

Step-by-step explanation:

From the pattern I noticed that y is pretty much 10 times the value of x. So when x equals 12, y will equal 120.

Hope this helps. Please mark me brainliest.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
