Subtract 1/2 * (z + 4) - 3(1/4 * z + 1) Use fractions in final form. (1 point)
To subtract the given terms, we need to distribute the coefficients:
1/2 * (z + 4) - 3(1/4 * z + 1)
= 1/2 * z + 1/2 * 4 - 3 * 1/4 * z - 3 *1
Simplifying each term:
= 1/2 * z + 2 - 3/4 * z - 3
Now, we can combine like terms:
= (1/2 * z - 3/4 * z) + (2 - 3)
= 1/2 * z - 3/4 * z - 1
Thus, the final form after subtracting is 1/2 * z - 3/4 * z - 1.
