Final answer:
To evaluate the expression ay 4z with y = -4 and z = -2, you substitute them into the expression. If 'a' is mistakenly represented as 'I' and 'I' = -5, the calculation is (-5)(-4) x 4(-2), which equals -160. However, 'a' is not confirmed, so we cannot be sure without the correct value for 'a'.
Step-by-step explanation:
To evaluate the expression ay 4z with the given values I = -5, y = -4, and z = -2, we simply substitute the given values into the expression. However, there is a typo here; it seems the variable I is not relevant to the expression, as there is no I in ay 4z. Assuming that the expression should be ay \(\times\) 4z, we proceed by plugging in the values for y and z and multiply as follows:
ay 4z = a(-4) \(\times\) 4(-2)
We need the value of a to complete the evaluation, which is not provided. Assuming a is meant to be the value I (-5), we would have:
ay 4z = (-5)(-4) \(\times\) 4(-2) = 20 \(\times\) -8 = -160
Without the correct value of a, we cannot provide a definitive main answer, but if my assumption is correct, the answer would be -160.
