Answer:
2.54 centimeters per inch
Step-by-step explanation:
All you gotta do is centimeters divided by inches
Answer:
10%×200=20
Step-by-step explanation:
25%×200=50
35%×200=70
Anything per something means that is a rate, so you will have a variable on that, such as x.
So $2 per movie, is interpreted as 2x
The $10 is a set price for a rental card, and will not change.
So a linear equation is interpreted as y = 2x + 10
Set x to 6 because you are renting that many movies.
y = 2(6) + 10
y = $22
To determine if the line is parallel, perpendicular, or neither to the given line, we must compare their slopes.
Given equation: y = -2x + 3
slope = -2
The equation of the line can be calculated by -a/b of the standard equation.
(1) y = 2x - 1 , slope = 2
Since, this is just the negative of the given line, the lines are neither parallel nor perpendicular.
(2) y = -2x + 5, slope = -2
Since the slope is equal to that of the given equation, this line is parallel with the given equation.
(3) y = 12x + 7 , slope = 12
Since the slope do not have a special relation to the slope of the given line, it is neither parallel nor perpendicular to the given.
