Answer:
y = 1/9 x z^3
Step-by-step explanation:
y is jointly proportional to x and z^3
y = k * x * z^3 where k is the constant of proportionality
y =12, x = 4 and z =3
12 = k * 4 * 3^3
12 = k * 4 * 27
12 = k * 108
12/108 = k
1/9 = k
y = 1/9 x z^3
The input to an exponential function is the initial value of the variable.
Answer:
lol wat r u doing .........
The first thing to do is isolate the x so get rid of the -2.7 but since is a negative you are going to add it to 10.3 so>>> 2.7+10.3 =13 x≥13 is the answer.
