Answer:
Step-by-step explanation:
(x - 18)/2 = -14
x - 18 = -28
x = -10
(y - 13)/2 = -18
y - 13 = -36
y = -23
(-10, -23) the other endpoint
the total is $6.10 once applied
and the sale tax is $0.40
135
2 x 54 = 108 and .50 x 54 = 27 so 108 + 27 = 135
3 * z
if u multiply them, u get 3z
is that what u meant? or are there options to choose from, or did u forget to add something else?
