Answer:
Step-by-step explanation:
she had $ 24 to spend on 7 pencils....and after buying them she had $ 10.
this means that the total of the pencils was (24 - 10) = $14
and assuming each pencil cost the same price....
14/7 = $ 2 per pencil
or u can set it up as an equation
24 - 7x = 10....with x being the price of a pencil
24 - 10 = 7x
14 = 7x
14/7 = x
2 = x <==
- Slope Formula:
So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:
Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>
