Answer:
(- 2, - 8 ) , (6, 0 )
Step-by-step explanation:
y + 18 = x(x - 3) ← distribute
y + 18 = x² - 3x → (1)
x = y + 6 → (2)
Substitute x = y + 6 into (1)
y + 18 =(y + 6)² - 3(y + 6) ← expand parenthesis using FOIL
y + 18 = y² + 12y + 36 - 3y - 18
y + 18 = y² + 9y + 18 ( subtract y + 18 from both sides )
0 = y² + 8y = y(y + 8)
Equate each factor to zero and solve for y
y = 0
y + 8 = 0 ⇒ y = - 8
Substitute these values into (2) and evaluate for x
y = 0 : x = 0 + 6 = 6 ⇒ (6, 0 )
y = - 8 : x = - 8 + 6 = - 2 ⇒ (- 2, - 8 )
Answer:
10ac
Step-by-step explanation:
We have been given the expression a · c · 5 · 5
We can multiply 5 with 5 and get 25.
Thus, the expression becomes
a · c · 5 · 5= ac25
We can rewrite the expression using commutative property
25ac = 25ca
Therefore, the given expression is equivalent to 25ac and 25ca.
Hence, 10ac is not the correct form.
First option is correct.
Yes it does because when u multiply 2 negative you get a positive but since your adding another negative it goes back to a negative
