Answer:
The question is incorrect. please write your coordinates in the form (x, y).
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 )
Since al is taller than bob and bob is taller then carl that would mean that carl is the shortest there and al is the tallest
Answer:
16a^2 + 4a or 4a(4a+1)
Step-by-step explanation:
Use the distributive property (or FOIL).
First, the 3a2 becomes 6a.
6a x 4a = 24a^2
4a x -2a = 8a^2
4a x 1 = 4a
Simplify.
24a^2 - 8a^2 + 4a
=16a^2 + 4a
Other options:
=16a^2 + 4a
=4a(4a+1)

Answer:
I believe its 9 hours.
Step-by-step explanation:
Divide 180 by 12 to get 15
So Linda makes 15 dollars an hour
Then divide 135 by 15 to get 9
Linda would need to work 9 hours to get $135
