Suppose you are given that z = c x2 y4 where c is some number. For a particular value of c, x and y, z is equal to 7. Suppose x is decreased by a factor of 2.6 and y is increased by a factor 4. What is the new value of z?
2 answers
Z = 7 * (1/2.6) * 4 = 10.77.
Correction: Z = 7 * (1/2.6)^2 * 4^4 = 265.1
