Find the slope for the two lines and state that they are equal (condition for parallel lines)
Slope of line AB
[y2 - y1] / [x2 - x1]
Slope of line CD
[y4 - y3] / [x4 - x3]
Condition
[y2 - y1] / [x2 - x1] = [y4 - y3] / [x4 - x3]
Answer:
128
Step-by-step explanation:
Quotient means to divide. So i.e you want to work out 640÷5.
A quick trick to divide by 5 (Without a calculator) is to double the number, and the divide by 10.
so i.e we get 640x2 = 1280.
Then 1280÷10 = 128.

Answer: $1000
Step-by-step explanation:
Annual demand (D) = 8000
Cost per order (S) = $1000
Cost per unit to print = $8 per book
Storage cost = $2 per book per year
The minimum total cost can be found thus :
√(2 × D × S) / storage cost * cost per unit
√(2 × 8000 × 1000) / (2 * 8)
√ (16,000,000 / 16
√ (1,000,000
= 1000
Hence , minimum total cost $1000
Answer:
A = 5x + 3y
B = 8x + 5y
C = 15x + 11y
Step-by-step explanation:
B = 6x + 2y + 2x + 3y
= 6x + 2x + 2y + 3y
= 8x + 5y
C = 8x + 5y + 7x + 6y
= 8x + 7x + 5y + 6y
= 15x + 11y
A = 7x + 6y - 2x - 3y
= 7x - 2x + 6y - 3y
= 5x + 3y
