7(z +2) - 3z =44
Distribute the 7. Distributive property: a(b+c) = ab + ac
7z + 14 - 3z = 44
Simplify like terms.
4z + 14 = 44
Subtract 14 to both sides
4z = 30
Divide by 4 on both sides.
z = 7.5

Answer:
A (0,3)
Step-by-step explanation:
The given trapezoid has vertices:
(0,6), (7,12), (7,9) and (0,12).
We want to choose from the given options, a point that is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2.
Note that the mapping for such a dilation is:

This implies that:




Therefore correct choice is (0,3)
