**Answer:**

She will need 7 more packs of plants to plant all 80 tomatoes.

**Step-by-step explanation: Since she already planted 28, she needs 52 more single tomatoes, therefore she will need 7 more packs since it's 6 tomatoes in each bag.**

**Answer: the restrictions on the domain of (u°v) (x) are x ≠ 2 and which v(x) ≠ 0.**

Justification:

1) the function (u ° v) (x) is u [ v(x) ], this is, you have to apply first the function v(x) whose argument is (x), and later the function u (v(x) ) whose argument is v(x).

2) So, the domain of the composed function (u ° v) (x) has to take into account the values for which both functions are defined.

3) The domain excludes x = 2 because v(x) is not defined for x = 2.

4) And the domain must also exclude v(x) = 0 because u is not defined for v(x) = 0.

5) So, in conclusion, the domain is all the real values except x = 2 and the x for which v(x) = 0.

Therefore the resctrictions are x ≠ 2 and v(x) ≠ 0

X= fancy, y= plain

x+y= 7

28x+ 15y=131

solve by substitution
