Answer:
x - 7
Step-by-step explanation:
Because Julian is 7 inches shorter than his sister, and his sister's height is x, if we subtract 7 from x, we get Julian's height, x - 7.
Answer:
Since there is one value of y for every value of x in (−4,8),(−2,4),(0,1),(2,4), ( 4,8), this relation is a function. The relation is a function.
3x -7 = 14
3x - 7 (+7) = 14 (+7)
3x = 21
3x/3 = 21/3
x = 7
