Answer:
$847
Step-by-step explanation:
Answer:
y = three-halves x minus 3
Step-by-step explanation:
Subtract 3x from both sides of the original equation.
-2y = -3x +6
Divide by -2
y = 3/2x -3
Divide the total price by the total number of books from each printer to find the price per book:
Printer A: $350 / 100 books = $3.50 per book
Printer B: $150 / 40 books = $3.75
Printer A has the lowest price.
Answer:
k = - 5/√3 = - (5√3)/3
Step-by-step explanation:
5x + ky = 20
y = (- 5/k) * x + (20/k)
Line equation: y = mx + b m: slope m = - 5/k
60° with x-axis (suppose it's positive x axis): slope m = tan 60° = √3
- 5/k = √3
k = - 5/√3 = - (5√3)/3
