Answer:

(6, -8)

Step-by-step explanation:

Solve this system by substitution: substitute (1/3)x - 10 for y in the second equation, obtaining:

2x + (1/3)x - 10 = 4, or (after multiplying both sides by 3):

6x + x = 42, or 7x = 42.

Then x = 6. Substituting this into the first equation, we get:

y = (1/3)(6) - 10 = -8

The solution is (6, -8)

dusya [7]

Answer:

The correct answer is: p - 8 ∧ restriction p ≠ -4

Step-by-step explanation:

(p² - 4 p - 32) / ( p + 4)

The existence of this rational algebraic expression is possible only if it is:

p + 4 ≠ 0 => Restriction is p ≠ -4

(p² - 4 p - 32) / ( p + 4) = (p² - 8 p + 4 p - 32) / (p + 4) =

= (p (p -8) + 4 (p -8)) / (p + 4)= (p - 8) (p + 4) / ( p +4) = p - 8
