Answer:
The lines are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are the same
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
Remember that
The formula to calculate the slope between two points is equal to
<em>Find the slope of the first line</em>
we have the points
(-3,-1) and (1,-9)
substitute in the formula
<em>Find the slope of the second line</em>
we have the points
(1,4) and (5,6)
substitute in the formula
Simplify
<em>Compare the slopes</em>
Find out the product
therefore
The lines are perpendicular
Answer : C. Caplet form is the most expensive.
Tablet form comes in 50 mg tablets and cost $75.00 for a bottle of 100 tablets.
50 mg of 100 tablets so 50 * 100 = 5000mg
5000mg cost = $75.00
So 1mg of tablet form cost = = 0.015
Capsule form comes in 75 mg capsules and cost $63.75 for a bottle of 85 capsules
75 mg of 85 capsules, so 75 * 85 = 6375mg
6375mg cost = $63.75
So 1mg of Capsule form cost = = $0.01
Caplet form comes in 100 mg caplets and cost $70.00 for 40 caplets
100 mg of 40 caplets , so 100 * 40 = 4000 mg
4000mg cost = $70.00
So 1mg of Caplet form cost = = $0.0175
Caplet form is the most expensive.
